Hi there...I have a 1979 Briggs and Stratton 8 hp which has the points and condenser and am looking for the B&S PART NUMBER for the solid state ignition conversion kit..perhaps you have a source for this kit...Thank you ..I'm having difficulty finding the part number....thanks again
Oops...almost forgot...here's the B&S engine model #190402- Type # 1809 01 Code # 79100512
The one I used was: Coil (retro-fit electronic) 398811 $69 The address of the guy I got it from is in the description.
Same model and type as mine...
Nice video, Its just what I was looking for. I have a 79 model 8 horse Briggs on a Dayton generator I would like to do away with the points for reliability reasons. Thanks for taking the time to put it out there for the rest of us.
Thank You!
Back years ago, I put clear tubing OVER the plug wire. Just slide it all the way to the coil and there ya go.... new insulation, looks good too
Awesome idea!
Great vid BYW . I've got 7 of those old tractors. Just love working on them.
I still enjoy fixing these old girls and I get excited when one is brought to shop for repairs
Hate the cheap built new engines
I have meny a time replats the coil with a car tip of coil & used a Battery to energize the coil & ues the pints in place to create a park it . A fully charged battery will las 4 days constant ues Often i used a Every battery charger to keep it changed up I often used a Soler panel to charge the betray today.
Nice video, exactly what I needed. Thanks
Thank you!
Hello TrollForge, Sometimes a mag will work up to about half throttle, then crap out.
people think that mags don't go bad but they do. not knowing mags go bad, they think
its the carb. dad put a new carb on his 7 HP Troy-Bilt tiller only to be rewarded by the
problem still there. I hooked an auto ign. coil to a hot-shot battery and engines points
engine ran like a charm full throttle. Then I used mags low side to provide current for
the ignition coil. The wire from mag to points went to ign. coil. from coil to points and
no battery needed, gives a mutha of a spark as well.
Awesome! You should be making Videos!
Your magnetic parts can is genius!
Truly, more profoundly frugal (cheap) than genius! ;)
I just inherited that exact same tiller from my grandfather.
It was left in the barn when my buddy bought his place 15 years ago.
I leave the points and condenser intact and just cut the wire going to the condenser. It will not hurt anything and the points plunger will always have pressure on i and it will n ever fall out. . Also on some of these briggs and stratton engines you can find used electronic ignition coils on ebay, instead of using the magnetron or atom or other electronic ignition conversion kits.
Thanks
i totally agree with you about rust affecting the performance of the ignition system
Thank you!
I just got the exact same model. .doing this right.now... great video.. had to sub. thank you
Thanks
The first time I took one of these motors apart I was 6 yeas old and my dad was mad as hell because I tore up the lawnmower but then I put it back together and I have done the same thing ever since.I hope you know half of what I know but your video shows that you only know less than half of what I know.
gert frobe haha! My "Dad was as mad as hell" moment was when he came down stairs to find the remote control car he took 3 weeks to build ( in the hospital after his 2nd heart attack ) spread out piece by piece in front of me when I was 4. I found it again 2 years later, put it together without the instructions (which never made it home from the hospital) and had it working, in an afternoon. I never claimed to know more than you, I didn't argue with your other comments, I'm not a mechanic, but I am a trained machinist, and I do know about woodruff keys.
Then you must know that the woodruf key from a B&S woodruff key is weak aluminun and will break as soon as the blade hits anything solid so it will save the motor.
Yes but the way it fits is dictated by the fact that it is a woodruff key.
Great job. Thank you
Thanks for this video . saved my brain!
I'm so glad it helped.
moist humid conditions with ignition indicate not only plug wires but coil..On a hot dry day ,spray the coil only with water and see how she starts.If problem occurs this is your problem.Old plug wires will cause the coil to constantly max out and well run hot ,crack and let the morning due in.Hope this helps.
ThankYou!
It works, just did that with spinning wire brush and coil core faces where the core is next to the magnets, good spark.sometimes I bake a coil in Mom's oven 250 for a few hours.
My Wife would kill me if I tried that!!!
baked magneto, gets the dampness out, sometimes it works.
@@raymondgarafano8604 I'll try to remember that!
@@trollforge My Mom thot about killing me 4 that. I sed, "look mom,
u want the lawn mowed or what? only way its gonna happen is if I have a good
magneto so the mower runs. . .
@@raymondgarafano8604 LOL!
Very good instructional vid easy to follow along and well explained... camera work good too! 👍
Thank You very much!!!
Still fun to watch.
Thanks
never beat on the starter clutch. Use an adjustable wrench to tighten the clutch
Thanks
Thanks for sharing
Thanks for Watching!
I did about ten seconds of editing and finally got to the end!
Haha! Skipping ahead like an ADHD Tween, is nothing like editing...
3:00 cowling was the word you were looking for
moncorp1 yes, that would have worked.
I'm sorry your dad had a hard time I'm sure he was a good man
Thanks
I can replace the wire on any coil,cut off the bad part and replace with a piece car plug wire, using a sick pin with the head cut off. push it into the center of the wire and tape . i have been doing this for thirty years. it works.
Yes, I have done that many times as an emergency repair, though I have never left it to see how it holds up long term. Care to share your experience in that regard?
I have one I did about 15 years ago , it still works fine
Perfect! Thank You!!!
I always think that the 30 minute video has more information in it
I guess that it's time for me to do a video editing video.
Or any video?
Always put the bottom bolts in first on the pull start cover.
Thanks
If you have rusty. Part to get off use Acetone and Automatic trens. Oil 50-50 .Their is nothing like it
Well George, I have to disagree with your last sentence. Diesel & ATF is so close to being as good, that it's not worth going out for Acetone if you have Diesel. As a matter of fact I just shot a video about that.
Your camera person should be up close on the points area so those that don't know what you're doing can get a good view. I can do it in my sleep but all I'm seeing is Mr sausage fingers😉
Also, idk why none ever shows how to pop the lid off the clutch housing and cleaning the ball bearings & housing and then applying a light coat of machine oil to the bearings to assure the clutch works freely. Also clean/ polish the crankshaft before reinstalling the clutch to avoid the clutch squeal.
Well then, maybe you should volunteer to come and operate the camera for me. In answer to your question, probably because when most people get to that point, they are in too big a hurry to see if their repair worked, and forget... I know that is my excuse...
It looks like an industrial engine but I expected a flyweights governor not an air or wind vane.
That is the Engine as shipped...
Don't waste time removing flywheel and points. Too much work and not necessary. Cut the wires and you are done.
Except I wanted to save the old points and condenser... and we were following the manufacturers recommended procedure. But yes you are correct.
I Put a nova ll in a 4hp Montgomery wRd powerkraft and still can't get it to spark. Was told there was another way of hooking it up if no spark. Would you know anything about that
I know this is an old video but I recently got an old 8HP B&S snowblower engine built in 1967 Model 170402 . It worked when I got it. I am currently cleaning it up and repainting it. I may upgrade to an electronic ignition system soon. I am on the look out for a air filter assembly as snow blowers don't need air cleaners . I do this as a hobby and enjoy learning new ideas from all the YT videos. I also bought some new decals to put on the engine when it's done. I have no idea what I'm going to do with it but I may find a use for it eventually. BTW these ignition coils prices have dropped considerably since you bought yours. Did you actually pay $69.00. I live in Stouffville, Ontario.
This was a "You can have it if you can make it run" deal, when we bought this place... Yes, I did pay ~$70 for it, but I didn't really shop around, I just paid whatever the local guy was asking, because I needed it "now". We are up halfway between Ottawa and Montreal, just south of the Ottawa River.
You may like to know condenser was the old word for capacitor.
True, but the older term is maintained by mechanics, to differentiate between what is used with points, and the old CDI (Capacitor Discharge Ignition) system.
@@trollforge true, I work on engines and computers so I use the new term for all of it
@@deltacx1059 I work on computers too. My Grade 13 electronics project was designing an XT, that was the year the 286 was released... Or the one following, a very long time ago in any case...
@@trollforge the oldest PC I have messed with was this "portable" version of a ibm 5150 (I think) I'm still quite fond of those.
Can you put on electronic ignition without removing the flywheel?
I have been told that you can, look through the comments, someone posted a link, I think...
At 6:41, why not use a puller, to pull out the flywheel, instead of whacking it with a hammer, even if it's a plastic hammer?
Because that's what they used to teach in school here in the early 80s...
awesome video! what is the model number on this tiller? I have a 917.297580. do you happened to have a manual? also do you know the size of the tiller tine engaging belt?
Sorry Christina, I got this tiller 3rd hand (at least...) and it no longer has the model/serial tag. I do not have the manual either. I don't remember if I ever opened that side of the machine, so I have no idea of the belt size either... If you take a sewing tape measure and wrap it around the outside lip of both pulleys that will give you the belt length, and measure lip to lip on one pulley that will give you the belt width. I specify a sewing tape measure, because the measure around tight corners better than a carpenter's tape measure.
It may be 3 pulleys depending on the engine engage mechanism of your machine, if it is measure around all 3, with the lever in the engage position.
Ok, will do! Mine is my husband's grandfather's old machine. Geez these things are beasts!
Yes they are...
trollforge, any tips or guidance on adjusting these funky carbs? I've only ever rebuilt, cleaned,and adjusted standard bowl and float carbs like on 70s model Kohler engines or small lawn mower jobs. I appreciate the mentoring. not all of us have a mechanic in the family to teach us, so i end up floundering thru.
Great video, I've decided to do the same
To my john deer 214 lawn tractor.need to make sure I understand what all comes out.
The points and condenser, as well as the coil
Is that correct?
That is what the instructions that came with it said.
Did you get it to run? My video ended!
Yes, I lost a piece of footage, I brought it outside and it started on the 2nd pull, and has run fine since.
CAN I install and electronic Ignition without having to remove point and condenser
+RANDY CUTHBERTSON I have never tried that, so I cannot give a definitive answer, it should work, but the points are moving parts, and do wear, so, could eventually fall apart and damage something...
The white wire going to the throttle linkage bracket.... I think it’s a kill switch wire. Correct? How is that connected to the switch mechanism that presumably grounds the engine and then stops the ignition killing the engine?
I have a 190502-1662-01 that the kill switch wire was disconnected when I received it.
Any help and or additional videos would be helpful. Thanks to all.
I haven't used that rototiller in about 2 years now, yes, the white wire is a kill wire. The throttle linkage, all the way to the slow possession contacts the wire and grounds out the system.
So you ride a Harley? looks like a skull ring. . .got an old 901 Sporty 1200 bike is a freakin blast
to ride.
I used to have an '85 Sporty 1000cc Last of the cast iron jugs.
Hi I am trying to add an electronic ignition to my old B&S 8 HP engine it's out of my vintage Cushman 3 wheel golf cart. The motor that you are working on in the Video looks almost identical to mine other than my motor has a pulley bolted on to the front of the flywheel used to electrically start the motor from a motor generator. My flywheel is 8 inches in diameter, can you confirm what diameter the flywheel was on the motor you were working on.
+Alan Bidwell Sorry, no, I can't, that motor is on a rototiller, and was the 1st thing packed into the machine shed for the winter. It is now inaccessible 'till spring..
C
Thank you for the vid. Like the jewelry. What about re-magnitizing flywheel? Best regards.
Ben Still if the blade of a screwdriver will stick to it, then the flywheel has more than enough magnetism, which was the case here. I'm not sure I would know how to remagnetize the flywheel if that was the issue...
Briggs & Stratton snowblower not quite sure on engine size where is it located again when replacing coil should it be from the same size motor does an 8 horse have to be an 8 horse electronic coil when changing from points ignition
I think the are made for a size range...
Do you know what coil I need to convert my ‘78 Briggs & Stratton 3.5 HP side shaft engine?
I want to delete the points,
Sorry, no. I just used what the guy at the parts counter said to ...
could someone please upload a video of the points wires going to the coil
Sorry I haven't had a motor apart since I shot this.
u still waiting 4 info?
Hey, I have the same roto-spader but I do not have the engine model and sears model. Can you post yours so I have an idea for parts? What is the new coil part number?
+0001buster Please see the Description. Sorry it took me so long to reply, TH-cam flagged you as Spam...
I would like to now what the model # is on the 8hp B&S engine is that you are working on?
Thank you
Carl Sinnett it is in the description.
Hello troll Forge I have a question did that engine come out of a Montgomery wards 15 garden tractor if so I was wondering if you could show a video of how you got the Cupler for the driveshaft off the front of the engine I am having troubles getting mine off I have that exact similar engine in my wards 15 but I can't get to the magneto because of that driveshaft cupler
Sorry, I have never even heard of a Montgomery wards garden tractor, and no, that is the original motor to that rototiller. I wish I could be more help, but I am not a small engine shop, I just work on the motors I own.
TrollForge that's cool
The woodruff key is basically a shear pin and he didn't get it tight enough against the flywheel. It will fail. Don't ever hit that thing with a hammer. For lack of a proper tool use a pipe wrench to tighten it.
gert frobe really? Ever actually see a woodruff key in real life?
I've been a mechanic for 47 years please show me something I haven't seen.
gert frobe you've been a mechanic for 47 years and you still don't know how a woodruff key works? You can't be very good at it...
I think you are confused.
thats not a woodruff key. A woodruff key is half moon shape
Are you the guy who plays Burt on The Big Bang Theory ? You look and sound just like him.
Nope.
why not leave the points crap there and just replace the coil!!!???
Because that's not what it says to do in the instructions.
I am upgrading a 1974 Briggs 4.5hp from an Ariens snowblower 832. Hard to read engine model #'s. Can you advise me which ignition upgrade kit I would get? Thanks.
Akiva Feinstein Sorry, I am not in the business, I don't have any catalogues. I believe the upgrade kit was sold for a range of displacements. If I remember correctly I bought the one for 5 - 8 HP engines, and again, if memory serves me right there was one for 3 - 5 HP beside it, I guess that would be what you want.
trollforge Thanks so much. Great video.
Why waste your time removing the flywheel and points. Just cut the wires and leave them in there.
The engine I need a coil for is 1966 Briggs and Stratton 6hp where will sell one in British Columbia Canada? Did you just use Napa? Thanks
No the place used is in the description, try Googleing small engine service for your area...
Your video is informative just not completely accurate, I do like your homemade parts dish. Put a little pressure under the flywheel and 1 good hit will release it'.
No, it is accurate, everything i did or said works, though I will admit there are a number of things that are not "best practices."
I could use some help I own a gx7 Montgomery with a rear engine Briggs and Stratton it doesn't start up right and I wanna get it up and running any advice?
+jester jest sorry to be so long getting back to you but "Tis the Season". I'm not a small engine mechanic, just been tinkering with them most of my life. Generally speaking if you can pull it over and it will not start the problem is either fuel or spark. If you have no or very little (weak) spark this upgrade should solve your issue. If it is fuel I know there are a few videos on TH-cam on how to strip, clean, and reassemble a Briggs carb.
Mine starts but doesn't stay running
jester jest
then my 1st thought would be that it is a fuel issue...
Don't ever use brass feeler gages use stainless steel they won't degrade when they short out.
Thanks
It sits in front of the screen
Sorry I've never seen any small engine coupled that way.
TrollForge oh ok
TrollForge I've been enjoying your videos keep up the great work
Thank You!
a good video would be fabulous, if your cameraman could have held the damn thing still! I suffered from a lot of dizziness while watching this. had to take a break in fact:
I'm sorry about that. The common misconception that TH-cam pays big money is a fallacy. At less than $50 a month getting a "cameraman" is impossible. If you suffer dizziness from watching video, you really should get your inner ears checked by a doctor. Visual clues are only supposed to be 50% of what makes you dizzy.
Yes there's a tinnitus problem as well. My point was that when watching a film posted by someone you haven't seen before, and the film quality's not so good, then a lot of people just switch off on the assumption (fallacious at times, I know) that the overall quality of the content is equally bad, walk on by and find something else to give them the information they need.
I was not in any way assuming that you get a big fat paycheck out of youtubing, and really do appreciate the hard work put in by all you people for this. There are an awful lot of nutcases out there who seem to think that five minutes of information can be stretched out to a half hour video, and a half hour'd better than five minutes...... drive me nuts! By all means I'll listen to chatter, but it must be INTERESTING, like for example, your video. keep up the good work! hope to be looking at some more of your stuff in the not-too-distant future! Regards, Iain
@@iainmel1 thank you.
Tastfuly done thought I was watching a cooking show..I ...2 HAVE BIG FINGER..a lil testosterone thrown into mix
:)
where's the closed caption I am deaf
Terribly sorry, but this is a hobby, so there is no one to pay for closed captioning.
Really bad idea not to use a wrench to torque the flywheel back down. Very good chance your flywheel will come off and injure someone. They make a tool to go over the starter ratchet.
A chance my flywheel will come off? I doubt it, hasn't happened in 30ish years of working on Briggs... And if you want to donate the $40 Cdn plus taxes and shipping, I will gladly buy a Briggs & Stratton Starter Clutch Wrench.
I'm sorry this didn't work out well for for you. Not everything always works out; that's what editing is for.
It worked out just fine, didn't you read the end card?
I must have missed it.
what did you replace your old coil with? What part number and year of coil...?
+fishlovr1 Please see the Description.
Taryl fixes all 19:31
th-cam.com/video/Yx6AF8APVEQ/w-d-xo.html
Says B&S will 'recharge' your flywheel magnet to work with magnetron ignition, BUT they MUST NOT receive a damaged flywheel or you lose your flywheel! YOU pay shipping, they 'recharge' free.
OMG! Thank you that was hilarious!
Grown man with this man rings should be illegal...not sure why you even removed flywheel if you was just going to go to electronic coil...didn't make sense any sense to remove all that just to silicon a steel plug in....Cut wires install coil and DONE...
It's called reading and following the instructions. You can read?
TAKE OFF THE JEWELRY YA FOON!....WHO IN THE WORLD WOULD WEAR THAT WORKING???? I get
Who would wear that shit working? People who are in the habit of paying attention to what their hands are doing...
yumcha it wasn't a fashion comment....it's a safety comment....working on such things + the jewlrey could lead to a finger getting ripped off. the rings get caught or smashed .dudes sporting nubs ...try working as an actual mechanic/machines walking into work with the jewelry on!
The engine and I both got a year older watching all the bling!
Changing to from points to electronic ignition is really a down grade. You are better off with the point ignition.
While I do see your point, that is not a very popular opinion.If this were a real work horse with easily accessible points, say like a HD Shovel Head, I would agree.
Charles Angell, I have no idea how that would work.
Lose the jewelry!
Why?
I suggest watching another video......there are better ways to do this
Feel free to post a link to better ways.
Wow, I didn't realize how much that would cost. around 70 bucks eh? This was a great video, i don't consider it a waste of time at all, however, if I paid a hooker and things ended the way this video did, I'd expect a serious discount. LOL
So if this is going on like yours was, where the thing would get hot and then jump spark into the head and cut your engine off and stay no start till it cooled off, AND!, you didn't have 70 bucks, Would it be a safe assumption that a guy could pull the wire off the plug, remove the side pull start cover , run a rubber hose Or heavy shrink wrap down the spark plug wire or maybe even coat it with silicone and put a rubber grommet where it comes out the top to keep it away from direct metal contact. shrink it all down if you had the shrink wrap tube, and put it all back and be good to go?
is there any other noticeable difference in the way the engine runs performance wise or any other thing?
I am just wondering if it's worth it really, I mean, I really like the idea but i am on a tight budget and I mess with these old lawn equipment all the time, I have a couple of Ariens 1970's tillers w/ the Tecumseh 7hp's and reverse , mid sixties edger, I just picked up a 72 mcLane also , and I have at least a Ton of Mini Bikes around here. all of which I pick up for dirty ass cheap.
Reinsulating the plug lead does sometimes work, but then sometimes it is the coil arking out too...
That electronic ignition won’t work with separated magnets on the flywheel.Guess that’s why the video ended suddenly...lol
I can see you didn't read the end card. It has been running fine for the past 7 years with no other modifications.
Ur wife play piano?
I was not trying to be rude or anything, since I play classical, but yeah too personal,
just wasn't thinkin'
No, why?
No, that's ok.
Nice long fingers could stretch over an octave or a span of 8 keys.
@@raymondgarafano8604 I guess...
He didn't even check to see if he had spark first. I give this video a fail!
Sorry, lost on the cutting room floor...
Neither did he bother to explain why the flywheel retainer has a seal in or which way the magneto is installed and why. He should have removed the spark plug to rotate the engine explain that removing the points and condenser is not required unless you scavenge the parts for another project. Judging by the jewelry that is most likely why he removed the parts. This guy is learning from other TH-camrs and then makes up his own. Give him credit for spending the time to make and post the videos. Just please do some research on how things work and include explanations while you are doing.
Lousy camera work. Might have just made an audio tape.
Any suggestions how to improve my camera work?
TrollForge / TrollFarm I need that camera “in there” where I can see in detail what is going on. It would be a little uncomfortable for you but you can move 12 inches to the right and let camera get a more straight forward shot. Or camera overhead or over your shoulder.
Doh't ever use a hammer on a briggs mototer
