The Mini Mac 35 is a great little saw. If it is one of the newer ones it has a chain brake and is self oiling.
Look at the front cover plate of the saw. If you look at the little hole down on the lower left you should see a screw head. Both of mine have Zama carbs on them. The better carb has an adj. Screw for high and low speed mix. If you think you want to rebuild one of these carbs you better have REAL good eye sight.
Everything is very very tiny. What kills most of these saws and is deadly to Zama carbs is gasahol. The rubber turns to little bits of stuff the size of pepper. They came two ways as far as chain goes. Either 1/4 or mini 3/8 chain. If you can get the gear change it to mini 3/8. ALWAYS use the little round air filter on this saw.

So many people throw them away or just plug them up. O yes, the 40/1 mix is correct for this little baby.
They are a great limb saw. If you need more info, let me know.
Parts lists etc. Gentlemen, thanks for the info. I now have more information than I had yesterday at this time. It looks exactly like the one in the information that Joe provided.
Today I emptied out the carb cleaner I sprayed inside the gas tank yesterday and it now looks very clean. I'm guessing that everything from the tank to the intake port will also need to be taken apart and cleaned. A parts breakdown shure would be helpful. I was surprised to see that it takes a 40:1 ratio, as I have a couple of the small Sears saws that take 16:1. It's a good thing I asked and that you fellows took the time to give me the info. It is appreciated.
