Holley 4160 (3310-S) continuing issues
I've had a couple of issues with my Holley for quite some time now, and have really just now gotten around to addressing them. Being that its cold out this way, I'd like to be able to use my (Manual) choke, but it's never given me anything but grief. At a certain point it the linkage travel, it will raise idle and and keep me from having to feather the motor, but it will still die if I try to put it in gear. Any more travel and the motor just loads up, lots of black smoke and chokes itself out. So my only solution is to sit there feathering the thing for probably a good 5-10 minutes until it wants to run.
I have a relatively big cam, 280h comps in a 383. I wonder if I'm dropping so much vacuum that the power valve is dumping during choke? I just rebuilt the carb, so everything is nice and fresh. Really didn't even need it, but this problem has preceded the rebuild.
The other minor issue is that there is a tiny fuel leak which I think is coming from the rear bowl. It doesn't leak while the car is running, but after its off and sits for 30 min to an hour, a very small pool of gas builds up on the passenger side intake, right under the choke linkage. The leak is so slight its almost impossible to trace. The carb gasket is moist only from the point of the leak or so to the back of the carb, not on the front, which makes me think it must be coming from the rear bowl.
Any ideas are appreciated, thanks guys.
