My auntie gave me a 1988 model 3 horsepower Briggs and Stratton powered Supa Swift lawnmower in 2008 which had a broken pull cord. I have replaced the pull starter gear assembly because the teeth eventually got brittle & stripped out,on Xmas Eve of 2019 I replaced the piston rings with Stens piston rings because it was beginning to burn oil at full throttle,it was also beginning to foul the spark plug electrodes with carbon as well & I decided to give it a freshen up because of that, the plug electrodes now run clean (grey), I still run the original 36 year old spark plug in it. The fan cowl does need to be installed so that the governor will work properly as well,the old flat head Briggs engines are a tough engine which will go forever !
It is really great to see a young person do something besides play video games. I have been working on small engines for 56 years and Briggs & Stratton are the best. Here are a couple tips that might help someone out. Those starter springs usually break at the end. One end will have a notch and the other end will be bent. Just file a notch if it is that end and heat and bend if it is the other end. If you have to heat and bend put it in water ASAP. To rewind the starter rope file a notch in the rope spool with a chainsaw file. Pull your rope into the notch and wind then release your rope. A lot of times those flat head B&S engines will lose compression due to wear on the exhaust valve seat. With the exhaust valve all the way down place your thumb on the valve to see if it turns free. If so remove the valve and with a flat file take a little of the end until a piece of tablet paper will slide between it and the valve lifter without dragging.
Being a gen Z guy myself I work on mowers like this a lot and I don’t find video games very entertaining I enjoy taking things apart like these mowers gen Z plays way too much video games and instead they should be doing things to sharpen their minds and make them smarter
Hey your a great mechanic. Proud of you got that old mower going again. Clean it up paint it up. May be a little tin metal over the holes. You know your stuff!👍
Good work, now you've got a side discharge, and top ! When running it without the air cleaner put the hold down screw back or it will draw unwanted gas right out of the tank I love to see an old engine brought back to life. When word gets around you can fix them they will start showing up on your door step.
I stumbled on this. Way to stick with. Find cool stuff, do cool things, and put it on the internet to show the masses that things can be fixed. Keep it up.
model 92908, those pulsa-jet carbs sucked, tank top warped, literally sucking in air so the auto-choke wouldn't open enough to run when hot, hard to re-start, too rich.
Funny I consider this a newer mower due to the side mounted recoil. Looks like it from the 80s or 90s if I had to guess. Stuff was so much better made back then that I was using mowers from the 60s and 70s in the 80s and 90s. These days everything is such junk that if you get 10 years out of a mower your doing great. Top that off with the parts unavailability on anything more then 10 years old these days and nothing can be practically fixed anymore. It can take months to track down a used or NOs part these days. It’s funny how we never had an issue getting a part for a 20-30 year old mower or something back in the 80s and 90s. I’ve had to replace most of my lawn equipment in the last couple years because parts are just impossible to find.
It is older than that. I recently found a Simplicity push mower on the side of the road for free with this exact same pull start configuration. The 3.5 hp Briggs motor on it was made in 1969 on mine. It had a bunch of mouse crap all over it but the elderly lady who had it said it sat in a garage attic for many years. I cleaned the spark plug and carb (tank was empty) and it fired right up without any replacement parts. I didn't even have to clean the points. I've used it to mow the lawn twice since then and have replaced a few things. The muffler and air filter were falling apart, the governor linkage was really worn and sticking. Parts for mine have been very cheap and readily available. I got a Chinese replacement carb for a 2008 Briggs quantum for a free pressure washer for like $6 on sale on Amazon. It works great too.
Oh yeah that’s a blast from the past right there! Tight work getting that running too I was surprised it did. What happened to the rest of your boys this episode they missed all the fun 😄 anyway good stuff keep it coming I’ll be tuning in next time
WD40 isn't a good lubricant, it's a water displacer for spraying on wetted coil wires and distributor caps during damp weather. Automatic transmission oil, engine oil, or hydraulic fluid are much better general purpose lubricants. I'm partial to transmission fluid for various reasons. You can use an angle grinder to grind a new thin collar end on the end of the recoil spring (they usually break at the ends). Look up the "Davidsfarm briggs" videos on TH-cam where he explains it. This style pulsajet carburetor Briggs start easier if you tip the spark plug end toward the ground as it primes the "float" (there is no float) chamber so the diaphragm pump doesn't have to do the work filling it at first. That 50 year old hardened rubber diaphragm is probably not pumping great, but replacements are available using the engine code. The throttle spring goes between the throttle itself and that rotating plate thing on top the gas tank. The kill tab is also part of that rotating plate and cuts the ignition at the minimum throttle position. There is another hole on that plate for a throttle cable so you can can operate it without having to stoop down. That metal tab for grounding out the plug wire is something I never knew. Very considerate of Briggs and Stratton. Good job. 👍
Interesting, that engine got a side mounted gear for a self driving mower. But that mower body was never made for that, so someone has already diy'd this mower a bit.
Being a small engine repair man myself, I think a lot of this video is bogus. You know much about small engines to be so young, but the needle being so clean, especially after seeing the overall bad condition of that carb, then no mention or show of the diaphragm, maybe you don't know what it is ? Kinda think you do. Well it would be stiff and not pull gas, plus you never really show that carb, suction tube nothing. Plus that head was full of carbon ,, score marks everywhere, but they will still run like that . At any rate heat the old spring red hot bend a new hook on it. Let it cool , heat it again. Hopefully it will hold and let you fix that pull start. If the spring isn't broken in half. Vertical pull starter. Might hane a notched end just have to take apart and see ? Keep on going, nice job.
lol hes doing just fine, the way those carbs work its hard for water to get to the needle, he did everything to the best of his ability and knowledge, there's always room to learn an criticism isn't the way to teach it
@chithranandaweerakkody3957 what type carburetor and what type engine does it go on, if any diaphragm is stiff or has holes it needs replacing, maybe if no holes are in it, soak it un brake fluid for several days, it might work again, but no too long. U can try it.

Thank lot of ur great advise ....further more you have any solution for carburetor diaphragm problem jof the same engine ❤
That pull string replacement could probably be found online I used to have a lawn mower like that
Wtg young man. You stuck with it and got that old banger to go!!
Great save!

Nice repair. Now you need to repair the recoil pull rope starter AND find or fix the rusted out frame. But nice to see you didn't give up. Thumbs Up!
That's dope man just when you think all compression is gone she comes back to life 😃👌
Nice job! Those old flat head B&S engines always come around.
Nice brother ❤
Nice job man
I appreciate you not giving up

Use a socket and impact to spin the engine on the flywheel nut.

I have an older mower with a gear like that that runs a self propell system that sits on the front wheels. Figured it was like that but good to know.
@@thelawnboyz5023 can't see and gear on any axle or any slot in the body for the chain to pass through to the underside.
Good job, Bubba! Hey Bubba, did you ever figure out the manufacturer of that mower like snapper, Toro, any of those guys?
There was a tag on the rear of the mower but when I wiped it off to read it all of the print came off.

Watching him as we speak 🤣

The deck needs to be welded
Yep, it's from all the way back to the early 1980's. Really vintage.
1972!
That mowing deck is rotted out. It's A recipe for disaster.
Where was it
@@gradyhernandez4699 in the woods
I recommend using PB BLASTER for that
You probably need ignition points for that nice little mower.
