Good writeup.

I have usually found that the final, fine adjustment is easier if you decrease the idle speed back to normal.....or slightly below.

I don't think this is going to be a factor for Canuck though. I believe something is amiss with his needle adjustment. Either he went too many notches or didn't get something back together exactly right.

The other posssibility is that the Canadian carb. is jetted different and he really didn't need to do the mod in the first place. I don't think we have heard from anybody else having a similar problem caused by the needle mod. Might be something else causing it too.....like the choke not going completely off or a clogged air cleaner...........?????
