Well everyone im having some issues with my car and I dont know what to do. This thing has been a pain in the ass for the past month. Specs are at the bottom of the thread.
I had a cracked base plate for my carb so I got a new one from Proform. I went to put it on and when it was all said and done there was a vacum leak but the car was drivable. When I went to the gas station it was lugging and loading up really bad.
I took the car to a guy by my house today that is supposedly really good with carbs. He messed with the idle mixture screws on the metering blocks. He told me it had a vaccum leak becuase there was 2 gaskets between the carb and the intake manifold. When I left I got on it and the thing ran amazing. It had really crisp and fast throttle response. Anyway I took the gaskets off and put a new gasket on between the carb and manifold.
I go to start the car and the thing is idling at 3k and is racing. I turned the idle mixture screws on the metering blocks out a turn or so which brought the idle down to 1k. I took it around the block to see if it was ok. The thing ran rich and it was just terrible. I ended up taking the car to a friend of a friends and he took a look at it. It turned out the linkage from the primarys to the secondarys was too short and was opening the secondarys at idle.
That problem is solved. He adjusted the idle mixture screws and the thing bogs when you go to give it WOT. It clears out and pulls pretty good. When you push the accerator pump to give it gas while going to rev it WOT it its fine.
What can i do to fix this issue? I was told i need a bigger squirter or bigger accelrator pump. The jets are 71 in the primary and 72 in the secondary. The timing is where it should be. The float levels are dead nuts on. Idk this thing is giving me headaches!!!
Heres the setup
306
X-Cam
GT40P's ported polished
Weiand Single Plane Intake
Holley 650 double pumper
MSD 6Al and Blaster Coil
FRPP Wires
4.10Gears
The block and heads are decked but im not sure how much. I can find out tho.
