When I bought my Vega it had an Edelbrock 1406 on it. The owner told me he changed the jets and metering rods to "tune it." I now know that the 327 had a bad cam in it, so obviously the metering rods and jets were a pointless attempt at getting it to run better.
I pulled .070 x .047 rods out of my carb today and put the stock .075 x .047 rods in. Changed the primary .101 jets back to stock .098 and the secondaries were unchanged at .095. What does all that mean?
I'm assuming that the .070 rod (smaller) allowed more fuel to flow, and coupled with the larger jets created a very rich condition? Per the 1406 manual, the .101 jet is 8% (two steps) larger than stock. And having the stock secondaries with the smaller rod continued the rich condition? I do know that the car ran pretty rich, and one time dieseled for about 45 seconds when I shut it off. Would running this rich kill power, too? I know it's pretty hard on the cylinder walls to have that much fuel entering the combustion chamber.
Am I making sense? I don't know a lot about the actual functional parts of a carb. Trying to learn, though. I guess what I'm asking is whether my car should run better now than before? It smoked a bit on acceleration.
Thanks,
Colin
