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?

The two front cylinder are dead? That brings to mind a really really bad possibility....
If the other checks don't turn up the problem, pull the lifters from one of those front cylinders. If you find one or both are chewed up, you have a flat cam. (IMG:style_emoticons/default/sad.gif) You might be able to tell just by looking at the movement of the rocker arms on one front cylinder compared to those on the rear cylinder. Not sure. I really really hope I'm wrong. --DD |
