Stalls on idle in gear

Okay timing is set. Still not running very good in gear.. being a cool day here it was not acting up like on a real hot day.
We sampled a few dif carbs today and its looking like its not timing or carberation as the poor idle remains once in gear....
THe motor has no issues when you take off... runs like a bandit...


So tomorrow we are going to do a leak down test and gets some %'s

THen we will go from there ....
