RE: Conversion to Gas?
the concept is the same, it's just the fuel mix. what you need is a fuel mix that will ignite the glow plug. If the supertigre has bushings on the crankshaft then you will have to run more oil than the guys running the mix in the weedeater type engines. The fuel mix they are running on is 2 parts premium gasoline to one part 10% nitro 10% oil glow fuel. You could probably run on that mix with a little extra oil or modify the ratios in other ways...
