Wet plugs 4 and 8

[llwalkman]

Hi, new to the forum, but a long time reader. I have read alomost every thread regarding webers and it has help alot to get my setup somewhat completed on my mustang. One main problem that has me scratching my head. PLugs 4 and 8 are wet with fuel. Fuel pressure is 3PSI, I reset the floats on both carbs, cleaned the carbs. Made sure the floats moved after putting them back together (one was jammed on the float tab). Mixture screws have no effect on the cylinder. I am still trying to dail in my webers but feel I cannot go on until I get the wet plugs figure out. Any help is appreciated. Thanks

Hi, Walkman.

Check if all cylinders fire on idle by exhaust runner temperature.

First check your plugs. Make sure all are clean from oil or other greasy deposits.
Close mix screw on 4 & 8 while idle and let it run for a while. Any difference? Now turn the mix screw just free from the seat. Any difference? Any further, small movement might make a huge difference. This might take som time to figure out....

If you don't get all cylinders fireing, there has to be some other problem
- No spark at those cylinders?
- Damaged mix screw or seat?
- Other carb problem. Too fat mix screws?
