HELP me I.D. my Mac

[StihlaMan]

I have been all over Mike Acres site. this saw has the stickers wore off i have a few low quality pics to go by. It has a rectangular muffler a yellow filter cover and a few numbers on the bottom of the block( 1-41 00515). i would love to restore this saw but need some info before i set forth down that path.

I believe the 1-41 is the model of the saw. I think it is only a two port saw the third port was left not machined.

Looks just like my 250.See if you can find any casting numbers and I will compare with mine. Steve

Well i must have overlooked the 1-41 on Mike Acres site i think i looked at every other model though. i thought it could have been a 250 but the filter cover is different. does anyone know of parts that are interchangeable amost different models or someone with a good ring and piston. if i tear it down maybe ill find some casting #'s.

I just went out to my shop and the cover is the same.I believe there was a couple or 3 different 250's produced.
Not a saw I would want to run all day!!
She is fun to crank up once in a while though. Steve
