Stihl .050 AV cracked crankcase

[mayor]

I have an older .050 AV stihl that I'd like too get back together...trouble is...the crankcase has several small cracks in it.....was this common too this saw?...it ran when I took it apart. If anybody knows where I can get a case...I'm in need. I posted it in the wanted section too. [email protected] or (304)208-0672 (Tony)
This thing must have a 32" bar that is brand new with a new chain.....it ran good but was either getting gas in the oil or points or something...been a while since I took it apart and cant remember the problem.

Are you sure it's not just the paint cracked?

Don't take this as 100% true.
But I think the 051, 075 and 076 cases will work.
050, 051 have cylinder screws 075, 076 use
cylinder studs. At some time their was a crank shaft
change. You can do a search here or someone else will
come along and set us both straight

Is the crack through the crankcase or just the flanges that hold, for example, the recoil cover? Stop drill them, degrease , jb-weld with a stainless mesh scafolding makes a great fix.

JB Weld will fix a lot of cracks - gotta be CLEAN, no paint, oil, etc. For the 4 or 5 $$ it costs, it's worth a try.
