I know I am going to get beat up hard for this one but here goes. I have been trying to tune my carbs for a while now but have had no luck. I got the car to idle great ( I followed Rich`s advice by taking the linkage off and tuning each side individually. I got all 4 cylinders reading the same with the snail. I reved the engine a little and it started to pop through the cylinder #2. I let it idle for a while and pulled cylinder #2 wire and the engine continued to run the same. I pulled the wire for cylinder #4 and it still ran the same. I than pulled #1 and it almost stalled and the same was true for #3. I was puzzled that it would run so good on 2 cylinders. I turned the engine off and started it with cylinder #2 and # 4 off. It started up and idled fine. I verified the plugs were good by swapping them in the cylinders that were good and I swaped the wires as well. If my timing was way off could this cause this or is more an issue with the cap and rotor? I am so close but this is killing me because I cant tune it if it is not running on all 4 cylinders. Any ideas what is going on?

Im not sure which distributor that is, its either an 009 or an 050
If its 009 you have the correct distributor cap. If its an 050 you have the wrong cap. I can come over with my test meters to sort this out if you are around later this week. Its something simple but its easier for me to do it in person. I still suspect the carbs, but we can at least rule out the ignition pretty fast. If we spend an hour or so I am sure we can get it running right. I would have last time except the o-rings would have made it a waste of time... One more test. Take a flashlight. With the linkage disconnected on the carbs When you turn the key on...fuel pump running, car not running. Press down the carb throttle and look down each venturi to see if the accel pump is actually squirting fuel. It should do it when you press down the lever just once into each venturi. Check all four.
