I have a Craftsman snow blower with a Briggs engine. Of was purchased in the neighborhood of 2005-2006.
link to model It only got used once or twice this winter, but the belt started slipping so it sat. I really didn't need to use it and I didn't want to mess with fixing it in the bitter cold, so I left it sit until now. I ordered a belt and put that on today, but when I started it I noticed an awful lot of smoke. I had it on some saw horses so I could reach the belt without it laying on the ground and noticed that there was smoke shooting out of the bottom of the engine instead of the muffler. I put my hand underneath it and there is hot air shooting out of it while it is running.... not nearly as strong as the muffler but I'm sure it shouldn't be doing it. I started to disassemble it to take a look bit didn't have enough time to get a good look. Could it be as simple as a gasket or am I likely hosed with a repair that would be more expensive than replacement? |

As mentioned, it's a Briggs and Stratton engine.

Tecumseh Engine? What Horsepower? If it is around 5-6 HP I would go to Harbor Freight and get a Predator engine and put it on there. Sounds like you are getting blow by past the rings. Tecumseh engines are garbage. WOW Fact is Briggs snow engines were crap and were not used before the demise of Tecumseh, That is the only reason they are used today. A 20+ yr old Tecumseh powered snow blower is a common sight. Hell mine is at least 25 yrs old |

Here's an interesting update... I finally got time to work on it today. I took the head off... and there's no gasket at all! 
How the hell does that happen? I would love to see a pic of the inside of the head as well as the top of the block before you clean it. That's interesting. |

It's a silver gasket and can blend in very well with the head. Quoted:

But, the OP isn't known as a bullshitter so I'm interested in seeing how it's even possible for an engine to run without a gasket. If so, the head and block should show evidence of leakage somewhere. One possible issue that the OP may have....if the engine was running without a gasket, then the hot exhaust gases were being pushed somewhere they should not have been. As a result, there may be burning and pitting on the mating surfaces which may prevent future sealing. That's another thing I'm interested in seeing if there is evidence of. |

Briggs and Stratton engines were FAR better than Tecumseh. Some of the older Tecumseh engines on some riders were very high compression and they made a lot of power but they were short lived because they beat themselves to death. |

I could have sworn that I was just feeling metal. |

It IS metal and it blends VERY well with the head which it seems to stick to far more often then the cylinder top. As long as there isn't any evidence of leakage, I've used them several times, just being careful when torquing them down. I'd replace them if it was on something that required some effort to take parts off he reach it. |

If it shows up tomorrow I'll put it on there and give it a whirl. I looked for any cracks or signs of why it would be leaking and didnt see anything that stuck out to me. If it doesnt work, then I guess I've wasted more on less. |
