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?

While I have never heard it run due to the missing Idle Jet o-rings, I still suspect the carbs are the culprit.
Joe was handed these carbs with the air mixture screws in a bag... This means the carbs have never been setup back to matching specs. I feel that considering he has compression and spark, we are back to a fuel delivery issue. I will drop by today to see if he is around. He may be off at College today dropping his daughter off, but its close enough to drop in. If I can convince him, I will take the carbs with me and set them up properly so I know the carbs are right. From there, I will put the carbs on and get it running right. for me, with known carbs, its probably a few hours to get it running perfectly...just cause I have done so many... Valves, points, wires, timing, carbs, sync, etc... I think this may be Joe's first aircooled car...so the amount of variables may be to many at this point. Rich |
