Performance changes after a couple of minutes in the air
by Ken Mainstone
I have a vintage 20cc Super Tigre that has been rarely used since new. Getting correct idle and full throttle settings on the ground is difficult as the carb seems very sensitive.
After taking off with what seems satisfactory settings both full and idle, the engine after a couple of minutes in the air dies to what seems quarter throttle even with stick at full throttle. It is running on 10% Nitro
