I have a tractor with a B&S 17 hp and its been alluding me as to the problem Im having. I dont want to bias any ones ideas..... SO....

What would the symptoms be if a motor had an almost completely clogged air filter?

It would be like putting a rag up you're nose, how would you feel..? it would'nt work (run) that well. and be over rich.

well, I was looking for more of a SYMPTOM sort of thing, thinking someone MUST have had this happen

I was thinking rings, then a head gasket...but its looking like it was a clogged air filter. The machine would start and purr, but after a few minutes, would begin to sputter and puff blue smoke with each sputter. I noticed quite a bit of oil build up in the air cleaner housing....made me curious. I wrapped the air intake with an old clean shirt and let it run for 15 min..NO sputtering, NO blue smoke. And when I placed the air cleaner back on, it slammed back down from suction...telling me nothing is getting pulled through the filter and a LOT of oil and exhaust is getting pulled up into the carb from the vent. Could It be that simple??

YES:biggrin:

Sounds like your air filter is oil soaked and needs to be replaced.

exactly right....Im usually pretty good at diagnosing problems like this, but I NEVER had something like this. Its a 2007 machine, and I just got it a week ago...Im guessing its the original filter.
