OK guys, here it is.....
I am converting this engine for an airboat. Please no flaming for trashing a perfectly good saw...but I had a saw already and got this from a pawnshop for $20

I want to convert it to gas/glow (thanks for the 85+ pages on that guys).
First Q is "Do you think this is a good gas/glow candidate?"
Second Q is "Does anyone have a simple idea of how to drop the carb prophylactic??" I do not have a machine shop [

]
Third Q is "What is the smallest prop dia x pitch I could go with??" I want max R's and thrust, but low CG as well.
I will ask any gas/glow conversion Q's in the appropriate thread [8D]
