Need some help, Iconverted 40cc Poulan chainsaw to glow on alcohol and little under power for my scratch built P51 profile 85 inch wing. I would like to put on around 70cc but do not really want to change bolt pattern. Iam bolted through fuse into 4 bolt crank cover. Any ideas?

There is a thread here on RCU called gas-glow.
We are using 1 part 10/10 glow fuel and 2 parts gas.

The engines runs smoother and gain RPM, especially converted chainsaw motors.
We are using Walbro carbs.

I can't say it will make your 40cc act like a 70cc but more is better.
At this point you don't have much to loose.

Just a thought
