Hey,
New to the forum. Tried searching "adjusting idle" in the forum a few times with different terms but had little success... sorry if I am repeating an issue.
Installed a 66/80cc Skyhawk for the first time yesterday. While I am technically up and running, engine needs some fine tuning... specifically engine idle. The problem is the only way I can control the RMP's at all is by choking the engine. I actually can't fully disengage the choke because when I do the motor run's full speed. If I pull clutch lever in (disengage clutch) engine red lines (for lack of better terms). I have tried adjusting the air/fuel mixture screw (directions recommend 3.5 rotations from totally closed) but this does nothing at all. I have tried several air/fuel screw variations even totally tightened all resulting in the engine idling the same...full speed.
Secondly, I am getting a small drip from the bottom of the carb (there is a small screw there). Albiet very slow... it is consistent and I am not sure if it is related to the idle issue.
I am attaching 2 pics. One is air/fuel screw I have been messing with (which seemingly does nothing at all) and the other is a screw at the very bottom of the carb where the drip is.
ALSO - Because of the frame the engine has been mounted at a slight angle which also may be affecting things.
Please help me get this under control before I throw a rod into my nugget pouch.
