bogg issues
have a 64 with 327 and new dart heads manual trans. running holley 4160 carb. Not sure on what cam is installed but is lopy and has only 8hg vacuum at idle. Mechanical is 15 at idle 36 all in by 2500 which is a little early. B26 vacuum can. The problem I have is car boggs bid time off idle but runs fine otherwise. The bog goes away with the vacuum can removed. So when I saw this I thought I would just try ported vacuum but the problem with that is the ported fitting is reading full idle vacuum also. The idle speed screw is only adjusted in 1 1/2 turns so I don't think the primarys are open to far but not sure. Thanks Dave.

also a common problem is that guys back in the day over overtighten those 4 cam screws and warp the primary diaphram pump cover under the primary float bowl. Fuel would just leak out under. Is the pump cam in place?? Is the check ball under the diapfram on the pump in place and the check ball under the primary squirtes is in place...
Bottom line, if you do not get a big squirt out of the acc punp nozzles even with the slightest opening of the throttle plates the engine is going to bog

I recently had a bit of a hesitation on my 4160. I thought I had everything adjusted perfect until I installed an 02 gauge. I was actually very lean 16.5. So I changed jets and my hesitation went away to!
