I've got 2 of these Briggs powered mowers . I plan on running them for as long as I can. They are simple easy to maintain engines. All they need is a little TLC once every so often and they will run forever. The oldest one I have is going on 30 years old now I think it's a 88 or 90 model . The other is a freebee I picked up from the curb that had a busted flywheel shaft key after the previous owner had run it into something. So I fixed that one with a $4 shaft key and replaced the recoil as they had busted that trying to restart it ( it kicked back hard enough to bust the cord with the broken shaft key ) So for a grand total of $24 I had a spare lawn mower. Lesson here is if you have a Briggs engine like this one that won't start or kicks back trying to start , Check the blade to see if it's taken a hit into something. The carb gasket is a common fail and is easy and cheap to fix. If you have a busted shaft key then that's a little harder to fix as you may need a wheel puller to get the flywheel off. With all these new electric mowers and such coming out there will be people just throwing these mowers away cos it wont start first try. So get em while they are cheap and hold onto them as I think electric ones will have a very limited lifespan..you'll never get one of those to last more than 5 years much less 30 I reckon.

I love the simplicity of your videos. ❤ You are right, there isn't very many videos of cleaning the emulsion tube. There is a torque sequence for the carburetor. So the diaphragm seats well, and so the plastic carb doesn't crack when tightening. I can't believe the blade was on backward. LOL

Great video! It looked to me like the springs were not stretched enough to pull the governor vane back after you would let it go. Those engines will run forever if taken care of!!

Great, thorough video on the nice lil’ Briggs classic! I think the governor vane might still be just a little bit sticky, could be more mouse gunk hanging it up on the bottom near the engine block. I think that’s why it revs up and down for a few seconds when it’s first started. These are such great engines, glad you took the time to bring it back!

I think you’re right! Especially since the oscillation has been slowly disappearing the more I start it

Good video. I learned how to get the emulsion tube out of this type carb!! Thanks for the education.

Good service! Spark plug gap is usually .030 on most mowers and .025 for blowers and trimmers. Also, I would have checked the coil too, since you are there and checked the air vein bolt. Always best to double check. Good find on blade mounted upside down.

@BackyardRepairs 7 ай бұрын

Thanks! I saw your comment and checked again and you are right with the gap being 0.030", I must have been looking at the wrong thing when I first searched. Thanks for the tips!

Nice flip! I feel like push mowers are significantly easier and less complicated to fix than weed whackers, leaf blowers and even bigger riding mowers. Have you noticed that too? Cheers!

@BackyardRepairs 6 ай бұрын

Thanks! From my experience I think it depends on the manufacturer of the two-stroke equipment and how easily *they* want them to be repair/maintained for the price point they sell at. Some are vastly easier than others, sometimes to the point they're easier and quicker to fix than push mowers with the added bonus you can do everything from a bench instead of from the ground. Riding mowers are a whole other story lol, but I don't see a lot of those in my area.

I have one just like it and can't find any diagrams or anything, can u tell me about the berring or whatever has the little metal balls in it about the flywheel, mine fell apart and I don't know how it originaly was, I also have 2 other parts from it that I don't know we're they go if u could help me with that, they look like bolts but with flat heads and no threads, I have no clue were they go, I took the engine apart to fix it and lost track of where stuff goes, if u could give me some tips or knowledge that would be amazing thank you!

@BackyardRepairs 5 ай бұрын

Hey there, It sounds like you might have an older model with the ball clutch/ratchet type recoil. There should be the main “star” shaped cup body that threads onto the crank, 6 ball bearings, and then a thin metal cap to hold the bearings in that is held in place by the flywheel screen screws. I’m trying to think of what the 2 screws look like from your description and am coming up blank. To find the diagrams you’ll need to find the Briggs engine model number which should be the first set of numbers stamped on the blower cover right above the spark plug. If all else fails, feel free to email me some pictures and I can try to help from there too backyardrepairs1@gmail.com

How you clean it up Degrees or Power wash Or this wipe down With WD 40 Or pledge Furniture Polish

@BackyardRepairs 6 ай бұрын

I don’t clean them all the same way each time and just wing it based on how dirty they are. If they’re bad I’ll use degreaser and loosen dirt with a brush then spray them down with regular hose pressure. Some just need a rinse and a wipe down/brush. I very rarely will use a pressure washer bc I don’t like blowing the labels off. I’ve never thought to use pledge, does that work well?
