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

Hi and welcome to the forum

Thinking that since you had gas in the oil, maybe blow by from the rings. If you are using 10w30, try a straight weight 30 or 40, for the time being.

Thanks for the info. I will give that a try.

Ive read some other posts and some people have mentioned the breather possibly being clogged. I followed the rubber tube from the carb to the breather and its connected to a small plate that is bolted onto the engine directly under the gears that the starter attach to when cranking the engine. If i decide to open it up what should i be looking for that would indicate it is blocked?

Take the breather off, clean it with like spray carb cleaner. On the inside
(backside) check to see if the disc has a space of about .045 between the disc and the body. (This info is from an old BS service book)

But yes, a bad breather can cause smoking. The engine needs a vacuum in the crank case.

Let us know.

Please verify the color of the smoke.

White smoke = water.
Bluish smoke = oil.
Black smoke = rich mixture.

Unless you are putting something like seafoam, etc. in...

Thanks for everyones info. I called a small engine repair guy over and it turns out the mower was buring oil. The piston ring and head gasket needed to be replaced. Its running like new now.
