Sorry, you got me confused when you said main and secondary, I thought you were talking about the main jets not the idles.

Timing is set per the factory manual. I forget off the top of my head. [color:"red"] 10* ? ad [/color] with vaccum ports blocked.


I hope you ment 10* BTDC not after.

Do a quick check and make sure that the mains and aircorr are the right sizes.

Also, check your idle screw. The baseline is 1-1.5 turns in.(from where the screw first touches the throttle) Any more and you miss the idle circut completely.

No offense but I'm just trying to make sure the basic stuff is correct before thinking too hard.
