Mac saw engines continued - The versatile model 250
#2
Well it took some time digging thru manuals and IPL's. But I have specifics on the 200 and 300 series chainsaw engines. These are all fixed head models. The years covered are 1962 to 1975.

I will be posting the various part numbers for these models, including piston, rod, crank and cylinder. Also the production dates of each. Soon as I come up with a decent format to post here, the info will help you to identify your old saw to the year and even differences in each of them. The model 250 alone has at least 6 variants I am aware of so far over the years. Some big differences in them.
