Ron G. 14 Report post Posted June 24, 2006 My unit goes down, nothing just stops, >>> Do you need a mechanic or a urologist? LOL. White smoke is usually an indication of h20 entering combustion chamber i.e., a blown head gasket, but being an air cooled engine, I would suspect a bad valve, piston, rings, cracked head or cylinder. Have a compression check performed on the engine for starters. Hope everything works out for ya. Share this post Link to post Share on other sites
R. Williamson 14 Report post Posted June 25, 2006 First thing to check is spark. Second if you have spark, check compression. If you do not have spark, check the key switch by disconnecting the kill wire and try to pull start. The white smoke could have just been gas entering a hot combustion chamber without spark to ignite it. Those engines have two coils. I have not seen them go both go bad at the same time. There is a diode in between the two coils that goes bad but one of the coils would still have spark enough to make it run but badly I do not feel this is what you problem is though. If it has spark the engine is in bad shape. The compression test will tell that. Share this post Link to post Share on other sites
Mike Williamson 198 Report post Posted June 25, 2006 Check your air filter, and your oil level. I had a similar problem, other than the smoke, and it turned out to be an oil saturated air filter, from overfilling the oil earlier that day. Share this post Link to post Share on other sites
Paul Kassander 26 Report post Posted June 25, 2006 If you have a low oil shutdown (by the oil filter) try disconnection that. sometimes a piece of dirt will get stuck in there and tell the machine to shut down. On a more obscure note, look on the back (shaft side) of the main block. Up near the top center there is a bump out in the casting about the size of a nickel. If it is cracked or you see what looks like a ball bearing sticking out your cam busted through the casting. If this happend your valves are not opening properly and the motor will not run. This happend to me with 3- 16hp vanguards in the past. I was told I ran them out of oil BS. It was a casting issue and they eventually gave me a new short block for each. The engines were probably manufactured about the same time as yours about 2-3 years ago. I found out from some local briggs employees this was a semi common problem, about 1% (thats me). Hope this helps, if not feel free to call and I can give you some more ideas. Share this post Link to post Share on other sites
