converted_to_datsun Posted November 4, 2012 Report Share Posted November 4, 2012 There's a couple screws on the side of the carb towards the motor and the one towards the firewall is high idle adjustment. But that's on a stocks carb. Probably adjust It to where you want after the motor is warm Quote Link to comment

ggzilla Posted November 5, 2012 Report Share Posted November 5, 2012 Cold Fast Idle is 1800-2200 RPM Full warm idle is 700-800 RPM (it is not critical). choke must be fully open so take air cleaner Lid off and check. After changing the idle mixture must be adjusted. Quote Link to comment
banzai510(hainz) Posted November 5, 2012 Report Share Posted November 5, 2012 also ck with a timming light. Mqaybe dizzy needs adjustment. after warmed up ck the carb platre see if its still closed. That means choke is still on or needs ajustment. Then ck the timming also Quote Link to comment
