Im having a hard time getting my recently rebuilt 383 running properly. It idles rough, it does not hesitate. It was running way to rich and I finally had to install different jets and metering rods as per the tech support from Edelbrock.
The carb is a 1406 on a Weiand manifold. I have a Comp cam duration 268/280 Lift .477/48o.
I have a Firecore distributor. Im running about 34 degrees total advance.
A vacum gauge showed 14 inches and was vibrating slightly.
I was running Champion RJ12YC plugs, they were all black fouled and I installed Autolite 85
After I installed smaller jets and metering rods and readjusted the carb, the vacuum is now around 15-16 and the needle is steady.
However I feel it still is running to rough and it does not seem like a cam lope.
The heads were stock and the engine was originally a 2 barrel
Im thinking of doing a compression check. I have a compression gauge, the type that the gauge comes off and just the hose for easier use but im having great difficulty getting the hose started due to limited space, what do some of you use?
Any thoughts are appreciated, thanks
