It sucks when you hit the wrong button. Damn, I must have gotten up too early this morning and am getting tired. ; ) In a message dated 11/11/05 7:53:22 PM Eastern Standard Time, comwest@att.net writes: << RichardG=> The 3,4 bank does not fire OK, first I'd check to be sure he's getting fuel in the left carb. Looking down the venturi and giving the linkage a twist ought to do it. (This is basic, I know, but ...) If there's no fuel, put the old float valve back in (don't forget the thick washer!) and check again. Still nothing: check for a fuel-line blockage after the split. (All new fuel lines, right?) You said he checked for spark, I'll infer that he thinks he's getting spark OK on 3/4. He's probably right, but I'll add that it can fool you if you don't check for spark *at the electrode*. This is not a likely problem for two cylinders. Recheck that the spark plug lines are connected to the correct cylinders. The Type 3 distributor is set up at a different angle than the Type 1. (If he's using a Type 1 manual or Type 1 or 2 experience, it can trip him up.) => he can pump the carb, hear the sizzling and then sees smoke. If he's seeing it inside the throat, it's probably just fuel vapor from a warm manifold. Normal. This problem is very likely something simple. >> I agree with Steven, it's a simple problem, but it might take an hour or so to find it. Like Russ and Jim A. keep telling us, use an ohm meter on the wires (0 to 1000 ohms from end to end), and verify that they're good. The little brown insulators too (they should be 1000 ohms each). Valves should be checked to see if they're in spec (never hurts, and only takes 15 to 20 minutes to check). While you're there, check the point gap, and look for carbon tracking on the cap. I realize that this might start sounding like an FI check list, but it also applies to carbs. : ) Sometimes it's the little things that trip you up. :O My son's car had a couple of bad insulators, and a miss that we spent some time searching for. Once we corrected that it ran great. Now we can move to the fuel system. Verify that you've got fuel to both carbs. Now look down the throats and see if you can see a visible squirt from both when moving the throttle linkage. Also pay attention to any leakage or dribbling on after releasing (a sign of a bad needle and seat). I've had this crop up a few times in the last couple of years. Any carb not flowing any fuel from the throttle test, needs to have the top removed and the needle and seat checked for debris clogging the entrance, or fuel just not flowing (clog or restriction in the hose or passage way, or a possible pump trying to go bad). If you have fuel, and spark, then all you need is compression for the engine to run. any one of these missing will cause it to have a problem. I hope this helps.
