White smoke........

banjoman09 · Aug 26, 2019

This is not a tractor....but mechanical problem; I have a craftsman roto-tiller (Briggs engine)that runs and starts but emits all white smoke from the exhaust; runs a bit rough but was and still is running. Any ideas? Thanks.

If it's a fairly new issue and using some oil I would consider a new head gasket. Some of those B&S engines use one once in a while. gm

I would say head gasket.

Might change the fuel in the tank. Sounds like you got a gas/diesel mix, or something other than gas. Cheap and easy to check/fix.

Blue Grey ish smoke or black smoke are the only kind that a Briggs will produce. Since you said white, I will assume Blue grey and that means probably a broken ring and scored cylinder wall. A replacement engine from Harbor freight, or Northern Tool will be far better than a used Briggs that would actually be identical. Repairing the Briggs is possible if the cylinder wall is perfect. It would be unlikely to be a head gasket because there no oil or coolant in the head of an older flat head Briggs. If it is pretty new, and has an OHV head, it could be a gasket, but not as likely. Taking the engine to the big box store to match up shaft sizes and bolt patterns is easy. Jim

The cheapest would be the thing that?s at the end of the vacuum hose coming out of the carb brain dead right now can?t think of what it?s called

Check the oil level.

Could be over full, could be gas contamination has raised the level that it is blowing oil into the carb from the breather tube.

On an air cooled, no coolant.

How is oil consumption and which Briggs engine. The over head valve single cylinder engines will suck the head gasket between push rod chamber and suck oil like mad. Still ran fine but very smoky and oil level went down fast.

Second that

Is this one of the over head valve B/S engines?? If yes they are well known to blow th head gasket and that in turn causes a lot of smoke

ok and thanks for all the replys; will check oil level again and maybe change fuel out and start new; then may try head gasket.
Thanks for the help.

You haven't answered yet if it is a flathead or an OHV.

That's okay though, most times it's a guessing game here anyway with wildly varying answers in all directions.
