I tried your test and it turns a small amount and snaps back to where it started. Seems to me to be working?

I pickup up a dwell meter and with the gap set with a feeler gauge my angle was about 28.
I'm surprised it was running, but it is now set at about 41.5, right in the middle of the recommended 38-45.
The hesitation seems to be completely gone!

After I was done setting the dwell I decided to try the tach function on my new meter. It read around 350 and it says to multiply that number by 10 which would put me at a 3500 rpm idle.
The idle sound slightly fast to me, but there is no way its at 3500. I'm on the six cylinder setting, am i missing something?

My next step is to try and get the carb tuned properly. the needles seem to be a little out of wack.
As always, advice from people wiser then me is much appreciated.

Thanks for all the help everyone!
