Thanks for all the input guys. I have no idea what is "inside" the carb. I plan on taking the carb off this weekend and looking at the base idle adjustments and the transfer slots to make sure I am not hosed on that. At that time I will check the the jet and PV size so I know.

So this should have a decent idle at 900?

Any comment on the valve springs? Also, what is the best plug and gap for this combo?
