Wink Re: does anyone know what is the correct idle speed?

Sorry, I can only tell you the specs for a 49cc HS and that is 2500 RPM +/-200 RPM. And the tach will work on 2 and 4-strokes alike. I'd guess for the 66cc 1500-2000 RPM should be fine. I always idle a little higher than lower and my engines don't stall on take off or sitting at a light.

Default Re: does anyone know what is the correct idle speed?

I think i read somewhere that the skyhawk 66cc engine should idle at around 1400 rpm... but as stated before i think the sweet spot is easiest found by warming up the engine and then turn the screw counter clockwise until it almost dies then do quarter turn increments clockwise until it runs smoothly through out the entire power range...
