RE: Engine started but no throttle response at all????
No engine is timed at 40....The Zenoah manual for the 26 is 28 degrees BTDC, there is no reason to think a G20 would be any different...I don't have my G20 yet, but don't know if the ignition is timed like a Falkon at 2 BTDC...
Ask TKG, he has been running one for a while now...
