heres the plan, going to put the red bushing in the distributor. that will jack the timing up to 28 at idle. even though I don't think thats the problem at this point. it sets at 20 at idle but it's all in at 38 before 2000 rpm. but it could be . going to put blue pump cams in the carb and reduce the squirters and see what happens.

for that little of a difference I would just lock it out. no real reason not too
