Re: [FWDLK] more any clues



I took the vacuum advance off and took a look at it. I pulled the end off that the line to the carb hooks to and all sorts of crap fell out of the end. I guess it had been holding together barely since I bought it and finally died last night on my way home. Would that make it run this bad or should I look elsewhere also. I should have the new vacuum advance tomorrow around 1:30-2:00 in the afternoon. I REALLY appreciate all the help. - Duane

It's possible you have a vacuum leak elsewhere causing a lean condition, but that is unlikely. Have you checked the timing chain for slack? I can't remember if you said how many miles were on the car, but it could have jumped a tooth. Just grab the fanbelt and pullys, then remove the cap and watch the rotor. There should be very little hesitation in the change of direction at the distributor rotor when you reverse direction at the crank and pulleys. If the mechanical advance was stuck, I think the car would bog, but not spit and pop like you say. One thing you can do, is grab the line leading to the vacuum advance, or add a piece of rubber line too it. Then put it in your mouth, Yeah, I know that sounds bad,lol. and draw or blow on it. You should be a very little draw, then it will be tight. If the vacuum advance diaphram is blown, you will be able to draw air through it easily. At this point, I don't think you have a carb problem, so I would narrow my search down the ignition and timing parts. Unless the carb has went very lean for some reason, the carb wouldn't cause most of these symptoms, once you elminate the accelerator pump and vacuum leaks, which you have. One last thing, if there is a vacuum hookup for the dash to run anything in there, that is a sneaky place for a vacuum leak to hide, may want to check it as well, just like you check the vacuum advance. This one has got me scratching my head, but if we chase down enough links in this poor running chain, maybe we can figure out the problem, good luck! Let me know how it goes.

 Well I can't seem to figure the thing out. The ball is in the carb and it's adjusted right and pumping gas when you hit it. It just instantly goes to hell when you give it gas. Would the vacuum advance make it run like hell if it wasn't working? I've replaced everything else I can think of. When the cadillac I had before this had carb problems I finally ended up putting an edelbrock 4bl with an electric choke on it. It ran perfect from that day on. I don't think they make one for a two though. I'm not even sure that is it though at this point. After today I'm wondering if I should of sold that car.:)                                       Duane

 Sounds like the accelerator pump is not working, does the carb squirt a little gas whenever you open the throttle? There could be a little ball bearing missing that goes under the accelerator pump plunger inside the carb, or possibly the linkage is out of adjustment.

  I pulled the carb apart and blew everything out. I put it back together and checked all the settings while I did it. Everything is exactly how the service manual said to do it. It will idle now even in gear. I can give it gas slowly and it picks up fine. If I give it gas quickly it sputters like hell or completely shuts off. I HATE working on carbs. Anyone know what in the carb I screwed up to cause this? Thanks. - Duane
