Ron, Charlie, and Cotten: Thanks for the help. Yes I timed it like the Knuck, yep I did. I moved the timing back and smoothed it out some. Cotten, I put the disk in as you describe, bevel covers the holes and fits smoothly with the insert. It was backward on dissambly and the sharp interface seemed wrong. The book is actuly clear on this item and was simple to follow. I to have seen venturies in backwards and running, go figure. What made the most difference was two brand new spark plugs. I found some at a local Checker auto parts. Redid the low speed needle to 2 and 3/4 turns and the Hi speed close to 2. Made 70 mph on the way home and it is still HOT here. Third week at 103 plus. New plugs? Oh well, ya just have to figure. The surge is very small, noticeable cause I get stuck in traffic on base at the end of the day. The wife has her MC endorsement and is helping with the break in. With a Glide front and some risers it looks like an old Pan, from a distance. Turned a bunch of heads coming home and that was fun to. Panic, Thanks for the heads up on the timing.
