need help! car runs on 2 cylinders? Options

[TravisG]

HI all,

Just getting the car back together, can"t get it to idle, so I took off the carbs cleaned all the jets and passages, put back together, cranked the car and it revs up to 3000 rpms, try adjusting the carbs to idle down and find out that cylinders 3&4 do not affect the rpms (IMG:style_emoticons/default/confused24.gif) Then I take off the 3&4 spark plug wires and the engine still runs 3000 rpms no difference in motor HELLLPPPPP

Firing Order...check that first.
Make sure its 1432 clockwise looking from above at the cap.

Carbs,
looking down the throat, when the car is idling....when you open the carb on the side that does not seem to be running, do you see (look down the throat of the carb with a flashlight) a small squirt of fuel when you initially open the carb?

Check the inlet fuel supply filter where you attach the fuel hose....its a small screen that can get clogged.

Float level, this is a very common error that lots of people do not do right. Pull the top cover off and measure and fix the float level. Most carbs are wrong from the factory...

I am not quite understanding how your car idles. If it idles at 3k rpm, you need to fix that first.
Remove the cross bar linkage (disconnect the drop links)
get a syncrometer and check each throttle tube on each carb to see how much air it draws...this is another good diagnostic tool to see if your valves and rings are correct....if on cylinder is way below all the others...stop and fix that.
If one side is way below the other...stop and find the leak.

Thanks For All the Advice.

I switched the carbs from side to side and then the 3&4 cylinders ran and the 1&2 cylinders didn't. So my problem is one of my carbs. Time to do a complete rebuild. I am both happy(knowing what is wrong) and sad (down time in ordering kit and rebuilding), But at least there is a light at the end of the tunnel (IMG:style_emoticons/default/piratenanner.gif)
