Followed the link/sync procedure after rebuilding this motor and I cant get a good idle at the specified RPM. I can raise the idle and get it happy but off idle at a "No wake" speed it seems rough and the motor shakes a bit.

Can I just set my idle mix to clear the mixture up at this off idle speed and call it good or is there something else I should be looking at?
 
Sounds like it could be in the throttle cam pickup setting, but check the cam/roller to make sure they're not damaged. How are you measuring the idle speed? I tune the idle by ear, highest RPMs without surging or coughing (too lean or rich) and then the test back to idle after WOT running.

Otherwise you'll need to wait for the expert - Pappy, to chime in.
 
Lol, yeah, Pappy is a good guy for sure!

I forgot my cam roller has a flat spot. :oops:

Need to look where the flat spot sits at the moment as it does not turn very well.

My Pickup is spot on. Ill swap out the roller and double check everything before going out tomorrow.
