And another one forgets that this isn't a Walbro style carby
The EVO 10cc carb is a modified glow carb with a throttle barrel. No throttle plate to come loose
Meir, you really need to observe what's happening with the throttle and linkage when running the engine on the ground, also your radio has a servo monitor screen that will show you if their is any erratic behavior in the throttle sticks output.
