So I have this pretty sweet S-16H. around 1100 hours on it runs great but every now and then I shut it off and a few seconds later wham!! not every time though. Any Idears on how to get it to stop. It has had its oil changed every 50 hours since day 1 PO said he did and that's why hour meter is on it so I have continued with it also said its done that since he bought it in 1977.

the engine continues to spin after key is turned off. Unburnt fuel ends up in the hot muffler and ignites. Lowering the throttle to idle prior to shutting it off helps.

My experience with a k341 is it's best just above an idle. Each engine has it's own sweet spot for starting and shutting off.

might be adjusted just a bit lean...  what you describe was a notorious issue with engines in the later 80s and newer because they were calibrated lean and could not be compensated for. that is why carbs on newer machines have the silly solenoids sticking out the bottom of the carb to shut fuel off as soon as the engine is killed to prevent that very issue...  may be a partly plugged jet somewhere within your carb too.

 

how much slop in the throttle shaft? that will allow more air in and lean things out too.

just noticed your location... Kewanee IL huh?  Don't remember where that is within this lousy state think  it is kinda by Peoria?

I'm in IL too.... Kankakee area....  and have a few of these machines myself.

are these machines as hard to find in your neck of the woods as they are here?

 

around here if it says "Ariens" on it, chances are about 8.5 out of 10 it is a snow blower.

I have a GT18 with a K361 in it that does the same thing...occasionally.  I do run it on the rich side though to help keep it cool.  I've never fouled a plug, but she will puff some black smoke at times.  I try to let it idle a little bit before I shut it off.  It does help, but it still does it sometimes.  It's not so bad now that I'm used to it.  The first couple times made me jump!
