I have a TB110 Lawn mower that is in use for it's 2nd summer. I am experiencing a few issues. The engine sputters from strong to weak while I am cutting grass. If I push to fast while mowing the grass the engine will stop.
When I pull the choke it will not start right away. It takes a few times.

What I have done so far:
I replaced the air filter.
I replaced the spark plug.
I took apart the carburetor and sprayed cleaner inside and wiped it back down.
I cleaned the undercarriage with a broom.

What else can I do? I have not changed the oil, and using gas that is about 6 months old but I put the stabil inside of the gas. Any ideas?

 

Sounds like the carb is still dirty, post the engine numbers (xxxxx-xxxx-xx) so we can look up the IPL and see what carb it has. Have a good one. Geo

 

Thanks. It is a Briggs & Stratton 550 EX. I was only about to find the Engine Serial Number. I followed the video on Briggs and Stratton site to locate engine number but there was not one in any of the locations. I hope this is enough information for you.

 

The model number should be in one of three places. Have a good one. Geo
