With all the little thing I'm messing with' I won't know what works by the time I get to the track next year.
Yesterday I pulled the distributor back out and pulled the heavy advance sprng off. Put the dist. back in and fired it up. Set the timing to 36 and set the idle mixture and speed.
The engine idles so much better now. Steady idle that doesn't wander high and low. I think I was fighting with the advance weights at idle speed.
SO any way.
I blip the throttle and it now has a wonderful hesitation
Engine was runing around 150 deg so it shouldn't be because it was cold.
Prior to pulling the spring out it was running 36 total deg timing.
Now I don't understand why, if it's still set at 36 total timing, just all in at idle speed, why it now as this hesitation. It use to snap the rpm right up.
On a good note, on hot restat the engine just snaps to life, very short crank time.

 

Well I tweeked the carb but had to wait on starting it, my son was napping. So when I find a few min this week I'll fire it back up and see how it is.
The adjustment on the pump arm was way off, and I had a little binding on the secondary arm hitting the fuel line. I actually got it stuck wide open, I'm glad this didn't happen at the track. The more I look the more little things I find that could become a big problem.

 

Norm, just a suggestion. Try adjusting the timing to eliminate the hesitation, then read the total timing to see where it's at. Every engine is a little different and one size (i.e.; 36deg) does not fit all. Also, you could be running a little lean which would cause the momentary hesitation. I had a timing issue once and it turned out that the balancer had rotated and was giving a false TDC. Let us know how you make out.
