Is this a Stihl 064?

[AndyChalmers]

Hi, can you tell me if this is a 064?  Serial 149465316.  Im only guessing but not sure.  Ive just dragged it out my shed, been stood at least 5 years for me and alot more prior as purchased as spares/repair with bits missing.  I emptied old fuel, stuck some fresh fuel in, a few pulls and runs very well.  All others I dug out needed a good carb clean.  It needs quite a few bits as some missing. eg bar, chain, chain adjuster, brake lever assembly, back cover, 1 dog etc.  I'll prob try a chain/bar off another saw.  Is it worth fixing up just as a firewood toy?

If it runs as you say then yes .

Does your wrist need a splint and a day off after starting it?

 

Yup, 064.

Either an 066 or 064 - old from the lack of decomp and air filter design. Probably an 064 - I believe the 064 had a thinner flywheel and side cover than the 066. If you pop the muffler off, you can use a plastic nozzle pushed up against the inlet side of the bore, flat against the piston crown, raise the piston and nip the nozzle between the piston and exhaust port. You then measure the end of the nozzle to the nip mark and if 52mm = 064

54mm = 066!

If you measure the thickness of the flywheel on the fin ends, I can compare with a spare one I have here!

You ask an engineer a question, you get a technical response? The 064 flywheel fin is 30mm wide by the way! Not sure on the 066, mine is hanging off the workshop ceiling with a big expansion chamber on it!
