Chainsaw Repair

Thanks for the help and information guys. The neighbor came over and we were checking it out. I really hadn't done anything to it yet other than adjusting the chain. So we are thinking "will it run"?
So we put some gas in it and 1/2 dozen pulls later is running. Sputters & stops. Start it again and it does the same thing. 3rd try it fired up and smoothed out. We cut some wood for about 5 minutes and he says "what do you want for it"?
I says, how about $25. He gives me the money, we have a beer to seal the deal, and he takes it home.
Don't ya just luv a happy ending..
