Humm... I ran ten pin"El" in that log in NY. First pull through I leaned over to check the fuel. The nose knows, ya know, nuf said. Second pull I checked again. I never check twice. After, it got flipped just to see wit muh own eyes. Yup it's on gasoline with work saw manners and very good starting manners. Drop starts with out a hitch. Pulls like a OX. The chain is/was perfect for that work saw, effortless pull in the wood. Shoots nice roster-tails.
Also ran a Mac 125 I'd guess
