I GOT IT! I GOT IT! I reset the timing by the old 59 235 spec, reset idle speed to a little less than 500rpm. I have a analog tach, so, the manual calls for 475rpm. I would have to get a digital tach to be more accurate. Re-attached the vacuum advance to the distributor, cleaned carbs and checked jetting. It runs PERFECT! Lots of power and no spitting or backfire. Thanks for the suggestions and help.
Compression is 135- 140 on all cylinders by my Matco gauge.
