I friend recently asked me to get a MAc 15 which has had very little use - but has been sitting for over 20 years with no use - running. The saw was stuck - but I was able to get it freed up with solvent and have sanded & set the points, cleaned the carburetor and replaced the fuel line. I have very good spark to the plug and fuel delivery but no ignition - even with gas or ether sprayed into the carb - not a single fire.
The compression is only 100psi -which may the problem - though I have started saws with less compression when cold.
I have used Bon Ami in the past to reseat rings & clean up the bore - but only introduced in small quantity into the air stream through the carb with the engine running.
Any ideas short of a tear down would be appreciated.
This saw is 80CC with an 18" bar and is in new cosmetic condition - to nice to scrap.
