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?

I made a little mistake in my post--it`s the #2 and 3 cylinder not firing. I checked spark and there is spark but IMO it`s not great. I did a compression check on #3 and it is at 80~85. Again not great but it should fire and run. I also know that #1 has the lowest compresssion at about75. I am starting to think it`s more a carb setup issue or electrical issue ( possibly cap and rotor?). I checked the gap on plugs and it was about .028". I think that I should have the carbs rebuilt correctly because I dont have a clue what I am doing. If I keep touching it I am going to have a lawn orniment. I hate lawn orniments---. With that said I guess I should start from the beginning and check my valves clearance, than have the carbs rebuilt and go from there. This is so frustrating ( it seems like a no brainer).
