Chainsaw Repair

I ran 2 gallons of fuel threw it today. Seems to do well. Carries more rpm than a 660 in the cut. Are you running the m tronic carb and coil or just the coil. It makes me wonder how the euro carb would run with the euro coil. I do feel like to keep running the euro coil it is going to get dicked with some more. Wanted to run it for a week and get it broke in before I started to mess with. Based on what I have read they seem to like more timing.
