‘Stumble’ GONE

Killer6 said
Has the intake been off recently, or at all? I can believe it if not, they're notorious for the exhaust crossovers plugging up solid with carbon, choke operation is slow to won't
fully open in cold weather,...slow to won't come off fast idle,.....and Yes,... hesitation because the cold intake manny is lean now. I've fixed well over a dozen of those for
exactly that issue, the extra water temp may have been just enough to mask it at this stage if that's the case..............

Intake has not been off since we had it , who knows about the past.
We bought the 318 from a guy going to a 340 for his 72 Challenger.
He has a reputable shop that does his work.
He did say the mechanic there had rebuilt the stock carb.
He sold me a new distributor with it for cheap, saying that’s what he thought was the problem with its stumbling.
We installed it when we did the R+R and timed. It has had hesitation nevertheless until today.
