On my particular lawn boy push model with self propelled, I wasn't getting spark and pretty much followed the steps in this video. Even went as far as lightly sanding the contacts ( didn't have a spare coil at the time) But upon my diagnosis I followed a wire running basically from the coil back to where the bagger/safety flap that is inserted in the back where debris and safety feature is so nothing comes shooting out at user. Well on this model, the lever that gets turned and secures the inserted piece makes contact above and lower which makes a ground and enables the mower to spark and start. If its not properly set and/or doesn't make a good connection, ie dirt, rust whatever it acts as an open and prevents the mower from starting. It's almost like not having the bar depressed when starting. I double check this with the mower running and carefully tried to open the lever and tried to take out this piece. Upon doing so engine dies and kills it. Just thought that if someone has a similar model that doesn't start, check and make sure you have this piece properly set and secure or your mower won't start.
Nice fix DW6. You’re right about those spark testers. I wish they would make one that emitted a tone of some kind when there is spark, like when you use your multimeter. to check for continuity - would make it a lot easier, lol.
Great job, solid diagnosis, the guy that commented he's only replaced 3 coils in 60 years? This is the same guy that commented on my carb videos about only having to replace 3 carbs in 60 years 😂😆😂😆😂
Hey thanks for making this video! I have this exact model and here I am in 2021 and its not getting a spark. I am going to follow your procedure and see what happens! Thanks!
Of all the brands of mowers I've worked on over the years, Tecumseh's are far and away the brand that has had the most coil failure. The rest of the engine is well made.
Nice simple, straight to the point video! You could have checked the coil with a multimeter. It is always advantageous to save some parts for a rainy day! Curdos to you!
Noticed a Grizzly tablesaw in the background , I'm a Grizzly woodworking man also , love there machinery.... and your videos are very informative - thanks too .
First thing is to check for spark. However I find that almost always it,s carburation so I squirt some gas in the spark plug hole or the intake and if it pops it's got spark. saves a step. oh and I miss the kill wire sometimes but I'm a pretty hansom guy too. Tiss the cross we bare!
Ohm out the coil, good coil should read about 3.5 to 5.5 ohms. Lawnboy mowers are known to have coil issues. Replaced one this year on a 4-stroke Lawnboy.
I have this same model of lawnboy and I am having an issue with it going full throttle and I can't seem to get it to lessen unless I reach down and manually flip the throttle piece on the carb .... how do I fix this issue? I just replaced the carb on it and I believe I rehooked up everything I was supposed to
Hi! Thx for the nice video. I am just asking to help me a bit. There are two wires coming out from the Ignition Coil. One is long and the other one is short. The question is where the short one is connecting from another side? I just can see it's going up under the rotor but I don't the connector of the spot. Maybe you have a picture of this?
not always a dead short like this. my 18hp kohler vtwin was popp'en/backfiring/no power both coils tested high 14ohms. $90 for 2 new coils each tested 3.7ohms works good now
Got an old 1978 2 stroke lawn boy that says it needs a 32/1 mix. With the newer oils out now could I go 40/1 or should I stick to 32/1. What's your thoughts on that?
Hey I can beat forgetting to connect the kill wire - yesterday I was working on a Toro with the same Tecumseh engine and after putting it all together I went to connect the spark plug wire and realized I had forgotten to put the coil in! 🙄

will be trying this on my mower, thanks for the info!

Thanks for the video! That did the trick on my old lawnboy mower. Appreciate it!
Thank you for the video! I have the same mower that had same problem, which I fixed after watching your video.

Thank you.. I have the same exact model, with the same issue.. I am now optimistic about fixing it myself. I will update this comment afterwards.
is their a vidéo somewhere on how to take off the muffler

17 people apparently hate to learn, they have to criticize the man, it works so what exactly are these people dissapointed about. SMH
Very nice and straight to the point, video! Thanks!
Hey we all have screw ups when working of these small engines - no big-e . Good video there .....
I have this same model of lawnboy and I am having an issue with it going full throttle and I can't seem to get it to lessen unless I reach down and manually flip the throttle piece on the carb .... how do I fix this issue?

GREAT VIDEO
Thanks for the help
I at least know where to start
Thanks again
Awesome. Great video as always !

Great job awesome video!!!! Thanks for the share!!!
Great video now I have to tackle that green POS of mine thanks for sharing. 🙂👍👍👍👍👍
Where can I purchase a 21" lawnboy self propeled mower ??
Great video! Thanks for sharing. Would you by chance have the coil part number?
not always a dead short like this. my 18hp kohler vtwin was popp'en/backfiring/no power both coils tested high 14ohms. $90 for 2 new coils each tested 3.7ohms works good now
Nice walk through. Thank you.
Great video 👍 I keep a parts hoard myself, & it sure is cheaper than buying new.
Good fast fix👍
“Too worried about my looks...” 😂😂😂
Same here lolz!

good video thanks
that mower has a wired 2nd ignition cutoff if the bag is not attached. silly design but there beacuse there is no rear shoot cover.
Al's Repair and Restoration they came with a plug
THEMOWERMEDIC1 yes that's right but either the bag or plug have to be on to get a spark.
Nice job
Nice 👍 I hope that this is going to do it
Bob I tried to tell you about the kill wire but you were to busy to stop and listen. LOL
I haven't seen a lawn boy in over 30 years. are they still being made?
Dont like the idea Lawnboy putting the muffler under the deck, cutting dead grass or leaves could catch a fire.🇺🇸👍🔥
Hey brother. I don't do videos and still forget the kill wire. Lol. Thanks. :-)
The parts hoard pays off, again!
Don't forget the kill wire!
Hey can u give me the part number for that coil, i have the same lawn mower
try using sandpaper on the contact points of the flywheel and the coil they might just be rusty . edit : just/only
Very good video learn somethings off video
Very Good!... 49
A wish a Lawn-Boy
👍👍👍👍👍👍
We told you about kill switch lol
I kept telling you about the kill wire but you didn't listen. I AM NOT YOUR WIFE. Listen
I have been working on mowers for about 60 years . I have found maybe 3 bad coils.
Jerome Cook I've had to replace a truck load over my 30 years wrenching on mowers.
I have the same Lawn-boy, with the same coil failure problem. Thanks for the video!
mine did exactly what yours does when you forgot to attach the kills switch but no spark when connected. so should be a ground issue?
