try a leakdown test on that cylinder and see where the air is blowing out. great way to figure it out.

Plus, abodyjoe doesn't have pictures :) Can't wait to see the tech info G-J

I recently had an issue with my car bogging down and stalling. First, check your plugs, they can give you alot of information. Your car is delivering all the necessary things ie fuel, air, spark... but you are not able to sustain the mixture of these elements in a way that will sustain life...

What is your fuel pressure? Have you checked your floats?

:burnout:IT'S ALIVE!!!!!!!!!!!!!!:burnout: Finished reassembling the carb, and installed a new fuel filter and pressure regulator. She started great and sounds better than she ever did!!!! All I can say is Thank You!!! Thank You!!! Thank You!!!!! I really appreciate everyone's help I don't...

Whereas, these are all the pieces that I have.

The this is a picture of the pieces as shown in Super Tuning and Modifying Holley Carburetors by Dave Emanuel. The exploded view in the Holley instructions show all the same pieces.

***UPDATE*** Things aren't progressing very well. To start, I could swear the old gaskets were attached with super glue and cleaning was a bear! Then I got to the installation of the power valve and found that 3/8" inch pound torque wrench + 1/2" 1" socket= back to the store...

hmm.... the choke could be a problem, since it doesn't seem to be hooked up at all. Correct me if I'm wrong, but I think the car originally had an electric choke. This carb has a manual choke, but it was never attached to anything. It never had any issues before this tho, so....

Update!!!! Finally got my rebuild kit and started rebuilding my carb. Got it off the car, got the bowls off, and hmmm...... what in the world are those funny little screws. Spent the next few hours looking for a funny looking screwdriver to fit the funny looking screws then finally gave up...

Airplane gears? I googled and found this airplane dog, but no airplane gears..... Hehe.... but, seriously..... I can order the spring kit. It seems like a good idea since I don't have much faith in the way the past owners set this car up. I would like to know more about the different gears...

Well, I pulled the vacuum secondary off and there is a small tear in the diaphragm. So I got to the store Friday night after school and tried to order a rebuild kit and a diaphragm, but they are back-ordered from the factory. While at the store, I picked up a timing light, inline spark tester...

Ok, zip-ties are gone. As for the float levels, the Holley instructions for checking and adjusting the float level are: FLOAT LEVEL CHECK AND ADJUSTMENT: Primary and secondary float adjustments are set at the factory, but variations in fuel pressure could cause a change in these settings...

More questions..... 1. I'm not really familiar with working on carbs so I downloaded the instructions for my carburetor from the Holley website and started trying to figure out what is what on it and I still am at a loss as to how to tell if the floats are stuck etc. Can anyone point me in...

To everyone who has given their advice, thank you!!!! I now have a pretty good idea of a logical A-Z to start on in the morning. It'll probably take all weekend, if not longer, but I'll post what I find as I go thru my list. For all y'all who have attempted to hijack this thread to argue...

It has a dual feed, single pumper Holley 750cfm four barrel carburetor. Its the 4160 model. Manual choke, vacuum secondary

hehe...... I have definitely learned my lesson on spending a bit extra because "everything was redone less than x many miles ago"!!!!!! Sorry to hear about your car. I've been a bit frustrated that I spent $6000 on a car that I was told would be fine for a daily driver and 6 months later I'm...

It has electronic ignition with distributor.

Hey Guys, I'm hoping I might be able to pick y'alls brains...My car isn't starting and I'm at a loss here.... Here's the history I have on it I bought a 72 340 Demon back in November. I had to redo the front suspension, which took me a little longer than it probably should have, so it sat...

sweet! Thanks everyone!!

Went to remove my passenger side headers today and when I removed the bolt closest to the firewall antifreeze poured out of the hole. Any ideas????
