lawn boy 10515 problem

14 years ago

My Lawn Boy 10515 has suddenly let me down. This is what has happened now twice. The mower will be running fine and then, with a slight throttle adjustment, the motor comes to quick stop, accompanied by a squeal of sorts. The engine will then refuse to start back. If you wait a couple of hours it will start back.

The obvious signs of problems are the cables to the brake and transmission. They both have bad kinks in them. IÂve read that a bad module could be the restarting issue. Could it be the shutting down problem as well?

The cables are around $50.00 dollars each and a module cost slightly less. Where should I start troubleshooting? I hesitate to invest $150.00 and it ends up being the transmission or something else.

Any advice would be appreciated.

'My Lawn Boy 10515 has suddenly let me down'
Let's see - you neglect to perform maintenance/repair and the mower let's YOU down?
Sounds like the engine brake is engaging (the squeal) along with the kill switch (the stop). Repair/replace control cables and engine brake ass'y. as req'd.
Before buying new cables you might try unkinking them and using a penetrating lube in the cable housings.

Lawn Boy #8430 Problems

model 8430 is a 1986 1 speed capstan transmission. There should be a lock on the handle if desired to not use the Self Propel. Maybe it is missing. Go to the optional link. Go to parts. type in your model number. The diagrams will show you parts. Looks like a 1 speed personal pace to me????????? Toro bought LB in 1990. Are you sure that the brake assembly is not causing the starting problems? Here is a link that might be useful: lawnboy

10515 not running problem

This engine has to have good seals on the crank to run - so it will draw in fuel/air when the piston goes up, then compress it in the crankcase when the piston is driven down. You will see lots of oil and black goop around the seal if they leak too much (except your mower has one hour on it so there can't be any black goop there). They have to leak a little to let compression blow fuel/oil through the bearing to clean and lube it and lube the seal, but it shouldn't be a lot. The seal may have just popped out, too, which happens sometimes. By the way, have you pulled the muffler and taken a look at the exhaust ports? I know, it should be fine since it's basically new, but you never know.

I'm not sure exactly what you're needing but the entire safety switch kit is available as part number 93-4307. Mowpart.com sells the kit for $13.50. Good luck. Here is a link that might be useful: Switch kit

Don't know about cables, sounds to me like the engine is seizing perhaps from being straight gassed or otherwise over heated some time. When you say it refuses to start back up, do you mean the engine won't turn over or it will turn over and not fire?

Hey Walt- Thanks for juming in. The engine turns over fine,it's just doesn't fire. Once it cools it runs great for a few minutes of mowing and then does as stated. I've only had the mower since early last year. I can say without doubt that I've never put straight gas in it. I use the ECHO synthetic that others here have suggested.

The cables are in bad shape but otherwise the mower looks great and has been performing flawless. I hate dealing with cables. Brake and gear cables on a bike have always aggrivated me and Santa Claus.

@Joe Collins Sorry dude, you should've given her the house instead of your Lawnboy! LOL!

As far as finding one new....well, you won't. The EPA forced manufactures to stop producing 2-cycle lawnmower many years ago. I don't remember the exact year.... Early 2000s for sure though.
