I have never try'd 2 start it (as in pour fuel in it ) I know that is does turn over recoil starter works never checked spark or compression bought it in a lot of 5 saws at an auction cause there was a mini mac 6 that I wanted in the lot also have a mac 10-10 that I would also sell and a mac 610 I want 2 keep the mini mac 6 but if the price was right I'd sell it 2 ! These saws are just setting around and I don't have time to mess with them so I reckoned I put em up 4 sale so someone out there could enjoy them
