10247 Smoking Excessively
Hey guys, great to be back! Hope everybody is well!!!! My 10247 started smoking this year. I installed a new plug gapped to .035. Cleaned the air filter and lightly coated it with 10W30. I'm using Lawn Boy oil in 93 octane gas (32:1) of which I only buy two gallons at a time to make sure it isn't stale. It seems as though after about 30 minutes of mowing, getting toward the bottom of the tank, it will perk up and stop smoking. When I turn it off, fill the tank, and re-start, it's smoking again. I'm also going to say it's running a bit rough. If it was an old F motor I'd guess it needed leaned out with the screw on the carb? Alright, I'm out of ideas. Help!
