I got my G20ei with Walbro carb on it.
I don't like gasser's spring return throttle which seems to give a servo a burden.
I am using ROTO25 with that spring off the stopper so that the throttle moves freely
and it works with no problem.
I wonder why almost all throttle of gassers have that spring even though they are
used for only R/C. I don't think such thing is needed.
Anyone who knows why, please teach me.
