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?

Common problem.
You swapped the #2 and #4 plug wires. If you reverse the rotation, it will look right. It won't backfire, but it won't run on those cylinders either....BTDT. Check the plug wires... on a type 4 with the distributor installed correctly, the two towers on the RH side of a 914 should go to the same cylinders on that side. The other 2 towers should have the plug wires crossed. Excuse the crude drawing.. but I think it gets the point across. |
