Glow engine's are made that way because we use rod's. Gas engine's are not. The spring is, as stated before, normally on an engine in a weed eater, chainsaw, edger, etc. etc. Those do not use rod's for throttle, they use cable's and the spring is for return to idle. The spring is also, by design, a shim. It does play a role in keeping the butterfly centered.
you dont use a push rod in you gas planes???
If so you are looking for problems.
Guys like to argue on here. i will always cut my spring from the arm unless the instruction included with the engine say not to.
Why put a big strong servo to operate the throttle and spring lol to me that is just plain going against the grain per say. its not needed so i am cutting it.
Do as you wish.
I set up all my planes carbs to work on a pull rod, not a push rod.
Tell me, what are these problems that i WILL encounter?
