Stihl 039 - fix or skip?

Recommended Posts

While it's not widely published the fix on the Zama carbs is not a big closely guarded secret .In addition many times the carb has been blamed for problems they really didn't cause .Such as worn crankshaft bearings which allowed side movements to the crankshafts resulting in air leaks after the saw had been running a few minutes .

 

In just the US and Canada the amount of good crankcases on flea bay is stagering and they are cheap .This only points out that those 020 and 200T's that didn't die from a fall from a tree had their pistons cooked from air leaks and not all of them can be traced to a bad Zama carb .

Update:

 

got the oversize stud from Mr Solutions on Friday, along with some spare bar nuts and a new helmet. It went on a treat and my old 039 lives again, all for £2.35 and P&P.

 

Many thanks to all for their input and especially Spud for pointing me in the right direction. :thumbup:
