Push mower engine issues (power, idle, etc)
Greetings from the foot of the Blue Ridge mountains :)
I've got a Briggs and Stratton push mower (engine model 098900)that's running very weak. It seems to get better as I use up gas, and right before I run out of gas, it runs great. It also seems to stall out a bit as I push and pull the mower in and out of tight spots.
Here's what I've done so far:
- Sharpened the blade
- Replaced the priming bulb (it was split)
- Removed the carburetor, blew it out with compressed air, checked the pick-up screens
- New air filter
- New spark plug (old one was black...very black)
- New governor spring (the one that adjusts as load changes)
Another clue: the fast/slow throttle lever does very little...even if I moved it closed and open at the linkage itself, so it's not the cable.
I'm grateful for any hints you can offer.
