Jeep CJ Weber 38 problem...need help!
Im new signing up to this site but have had tons of luck reading previous posts, etc. Now I have a question because I am out of ideas...
My Jeep/Engine: 83 CJ7; 258; HEI ignition; BRAND NEW weber 38, new plugs, new solenoid, new cap and rotor for HEI, new fuel pump, new fuel filter, new pcv...basically replaced all of that when I bought and installed the new weber. It ran like a champ for a few days - was probably a little rich - and wasn't 100% sure that choke was working properly - but other than that it was great. I had timed it to 8* and it idled hot at 650.
I Let it sit for about 2 days without running it. I didn't need to drive it but went to crank it anyway. It started perfectly, ran for about 2 minutes and then died.
Jeep will turn over, runs VERY rough on a few cylinders (sometimes) and then putters out.
Extra info that might help:
I am not out of gas.
If it does start, it runs on what seems like maybe one or two cylinders.
It sometimes backfires before it dies.
Vapor is coming out of top of carb in between tries to start it.
I played around with fuel mixture screw - no help.
It won't even attempt to start up if I don't have my foot all the way on the gas.
I am out of ideas. It went from running perfectly to running like I have all but one of the spark plug wires unplugged. I have checked all the plugs, wires, etc...
Any ideas?... Thanks in advance
