Hello,

Im hoping someone can provide me with some help. I just purchased a 2003 troy bilt rider ltx1842 with B&S 18.0 I/C OHV engine. the model number is 13ap609g063. The tractor works great and does a nice job cutting. The other day i started it and after running for a few minutes it started to let out tons of white smoke. i turned it off and noticed that the oil level was too high. After removing all the oil from the tractor i noticed that gas was mixed in with the oil causing the oil level to be really high. I have sense then cleaned the carb and installed a shut off valve so the carb is no longer over filling and letting gas into the oil.

Now i have a new problem the tractor will let out a puff of white smoke when i first start it and when i turn it off. While i am cutting it runs great and the engine is not making any noises. Any ideas why this is happening?

also i took the breather hose off of the carb and noticed that while it is running a little white smoke comes out of the tube almost like it is moving from the engine into the carb. Is this normal?

Thanks
