Ok, so you might recall I recently bought an old Lombard that has been run @ 16:1 ratio...some of you guys said 32/40:1 would be fine, but it still is blowing a ton of smoke...short of opening it up is there a way to clean the cylinder/piston? Ran about a half tank of 40:1 so far, but still smoking (did clean spark plug and it wasn't bad). It does cut great and it won't be used all that much, but I don't just want a shelf queen (although it only cost me $50). Thanks.
I don't think so, coming right out "muffler" (empty can - loud)....haven't pulled plug again to look at top of piston, but am assuming it is black..didn't run long enough to heat up bar, manual oiler...can the bar oil get in the cylinder?
Yes, if there is a case gasket leaking then it can get into the engine via the crankcase. I'm not a Lombard expert but I've seen more than a couple vintage saws leaking oil into the crank case via the case gasket. Usually puts out a ton of heavy whitish/blue smoke that has a distinct smell to it.
I thought so...68cc so it is plenty powerful..lower top rpm than newer saws but nice torque...for that price I couldn't pass (he orig listed @ $150 and I waited him out)
As MM said maybe bar oil. Dump out bar oil and fire that mother up. I wouldn't cut with it but rev it up to burn out oil in crankcase.
