Lawn Boy problem

[Williy]

I had a cub cadet and ordered a small $10 fuel pump form
amazon and when I put the choke on turn key instant start
and make sure to reduce choke. Saves wear and tear on
the starter

It’s a pull start, small push mower.

Worked on these mowers back in the early 70's. Do a vacuum test. You may have seals leaking air into the crankcase pass the crankshaft. It's a 2 stroke like a chainsaw.

Success. I ordered a new primer setup, included a new primer bulb, the base and the primer hose. What should have taken 45 minutes took more like two and a half hours. The first attempt I’m guessing the primer hose didn’t get attached well, one of the screws holding the carb on is in the way. The second attempt I took the carb off, all the linkage fell off and I had to watch a YouTube video on how it went. That failed also as I discovered a gasket laying on the mower deck after pulling the start cord 20 times.

The third attempt was a success. I had my wife help me as getting the carb on with two gaskets and a metal plate (heat shield) in between the carb and engine is like trying to push a rope. It started on the first pull. I’m still not sure what was wrong in the first place but something with the primer, it’s base or the hose. Total cost was $7.55 from Amazon.

Congrats on a successful repair!

I ordered a new primer build just now off of Amazon, $7. It also comes with a hose and the plastic base the bulb goes on. I looked at the hose today and it looked ok but there isn’t much else it could be. I’ll post an update when I get the parts and install them. Thanks for all the suggestions.

All good posts. I had a lawn boy 2 stroke doing similarly. Shop said something inside like a crank seal went bad I think I remember right. I chunked it. Maybe you have better luck

It’s aluminum deck and has the power drive to the rear wheels so it’s a nice push mower.

I had an old seventish. No bulb on it. Crank second pull. Lawnboy isn’t what it once was

Lawn Boy was bought out by Toro a number of years ago. I'm not even sure they exist anymore. The 2 strokes of old on lawnboys are long gone for sure as the regs have killed them off.

Yes Lawnboy no longer exists.
