Briggs and Stratton 25hp Intek Smoking Intermittently

This one doesn't smoke all the time but will smoke moderately for a minute or two and then clear up and come back in a minute or two. I read the post on the wet/dry compression test, I am going to try it as soon as I can lay hands on a gauge. Any ideas would be appreciated. Also does anyone know if they sell a rebuild kit for 4457770168E1.

The first thing you should do is see if the engine oil is overfull and/or smells strongly of gasoline.

Also, what color is the smoke. Black is running too rich, blue is burning oil, etc., etc..

No smell of gasoline in the oil. Smoke is blue in color. Neighbor walked over an he said he had the same mower, and that they have trouble with rings. I may have got a lemon and at the least being stuck with a rebuild.

I'd check for a blown head gasket.
You can remove a valve cover, start the engine and look for a "mist" blowing out at the gasket toward the push rods.
Have a rag handy.

Thanks Bill, I will try and check for a blown head gasket tomorrow, Monday at the latest. They are calling for a lot of rain tomorrow. If anyone has a copy of the repair manual, it would be greatly appreciated.

Suggest you follow Bill's suggestion. I can send you a Service Manual if you like, address below, put in proper format and remind me, model number and what you want.

Thanks guys, looking more and more like rings. Trying to find out if there is a complete rebuild kit or if you have to pull the parts together yourself. Or what is the minimum I can get away with for parts. Cylinder gaskets, rings and head gasket?

RE: Briggs and Stratton 25hp Intek Smoking Intermittently

What leads you to believe that there is a ring problem? Are there signs of dirt ingestion past the air filter?

Rings??? Who said Rings????

His neighbor said rings.

RE: Briggs and Stratton 25hp Intek Smoking Intermittently

Were there 5 of them, only 4 lit up?

RE: Briggs and Stratton 25hp Intek Smoking Intermittently

Sorry guys, been out of town for a bit. I think the neighbor felt it may be rings because of his past experience with this engine. I'm still out of town and haven't gotten to work on it.
