Now it fires. Next step is to get the carb readjusted. Any suggestions?
If you have a vacuum gauge, attach it to the vacuum port, manifold, NOT timed vacuum, there are two ports on the front of the carb. If you don’t know which is which, manifold vacuum will have the most vacuum at idle and drop off as you accelerate... timed is the opposite, no vacuum, or very little at idle. Then you make slow, minor adjustments to the screws on the front until you get the highest vacuum reading. Start by turning in a quarter turn, see what it does, then the other direction, etc. If no gauge, you want to adjust it so it smooths out. The motor will lose rpm and run ruff if it’s too lean or rich, go slow, one side then the other, in, out, whatever makes it happy. I usually adjust till it just smooths out, then open the screw about an additional eighth or quarter turn providing it doesn’t negatively affect it. Repeat until smooth and happy. Keep the idle rpm in mind as you adjust and be sure it’s warmed up and the choke is open and not on the fast idle cam. I like to get them running as smooth as possible at the lowest rpm, depending on the cam profile, then bring the idle up to the desired setting. The timing is critical, so be sure it’s set... timing and carb adjustment should be checked together. If it has vacuum advance, block it to set timing, but reconnect to set the carb to set the idle speed. If you have never done it, perhaps a u tube video or the like would be helpful.The engine is the 350 chevy my buddy at work rebuilt. I went to Habor Freight and got the trust worthy inline spark plug tester. Lone be hold, no spark. I check the wires...good. Took the cap off and notice the green wire on the module was off. Reconnected it, put the cap on and had spark.
