Just fired up the Chevy after a two week hibernation & its running as rich as it ever has! Black smoke, stinking of petrol, sluggish, the car's just the same... .
Fuel pressure gauge shows 8 psi on tickover. Carb is an Edlebrock 600 4-barrel.
The carb is off Andy (58 Delray's) 58 which has a 350, so I guess it might want the mixture tweaking for my 305? Fuel pressure, is 8 too high? I asked a similar question a while ago on the NSRA but can't find the bloody thing!
Regarding setting the mixture, how? Many moons ago I had a special clear spark plug & you set the mixture until the right colour spark could be seen in the plug. I no longer have that & it wouldn't fit anyway! So, whats the best rule-of-thumb/basic set up for an Edlebrock as they are different to the Holley that I used to use?
