I read through all the articles on tuning and all searched, still having some problems.
Current setting: 75 main, 55 idle, needle is set with the clip 2nd from top. I tried 80 and 85 main (85 main wouldn't run well at all, 10mph tops). Idle jet started at 60, went up to 65 and it was much worse, down to 55 and it was better.
When I start from a stop, it bogs out and dies unless I go wide open. If I just crack the throttle a little bit while idling it dies. It only does then when fully warmed up. While testing different things, I found if I turned down the idle mixture to make the idle lean to the point where it was barely going then it behaved much better. Needle setting has little effect with the bogging.
Wide open, its running well but a little on the rich side. Plugs are a medium-dark brown.
To me it seems that my idle jet may be too big, but I see many posts with people running 55's and 60's with no issue and I don't want to run over lean. Does a 45 idle sound reasonable?
