Starting Problems, Help Needed

[YJeXtreme]

I just picked up this 1984 CJ7 almost 2 weeks ago. It was driven 1 1/2hrs to me, and ran up until I changed plugs and fuel filter... Immediately after installing the plugs and filter, it fired right up, until I noticed one of the filter clamps was loose, and spitting fuel everywhere. I shut it down, and since it hasn't wanted to fire...

Specs:
AMC 258 i6 / 4.2l with a "weber" 34 dgec conversion

I'm gettin fuel to the carb. I'm getting spark. I can spray starter fluid down the carb and it'll fire up for a second or two, then sputters off... From what I'm reading the 34 DGEC isn't a true weber, it was manufactured by Interco with licensing from Weber... I've not read the most comforting opinions or reviews on this carb, and debating on swapping it out... I have several MC2100s sitting around in my parts pile, I could easily rebuild and swap on, or I've debated ordering just the carb of a Weber 32/36 progressive unit....

Any help, suggestions etc... is appreciated. I've been building cars for over 16 years, but I've primarily focused on antique fords, old Ramblers, and also newer Jeeps with the 4.0. Webers are new to me....

Just a thought - fuel injection swap from a 4.0?

Might as well do the head too.

I'm trying to stay as close to original as possible... Its a low mileage jeep, originalpaint & interior & 99% rust free... Only mods are the weber, 3" lift & 33s

Spraying starter fluid in the carb then having it stall just after startup, indicates no gas getting to the engine. So there could be a carb adjustment to a bad fuel pump to question.

Always go back to what you did that changed things. Check your plug wires and distro connections as well as from distro to coil. Check your fuel filter. Did you install with the flow the wrong way. Recheck your connections, look for cracked hose allowing air into fuel line. If it ran before you did those changes than 95% of the time the problem can be fixed by tracing back. Good luck. Also, I love my 2150. You won't be unhappy if you install one of those on your rig.

Issue isnt plugs, filter or pump , it ran for 5-10mins after the changes. I'm going with junk carb... Found a deal on Weber 32/36 progessive... Prev owner told me of issues with it staying running, and adjustments a person made to carb... I think they disassembled & damaged the carb...

Ended up being a junk filter that i bought... Also completed the "Nutter Bypass" that prev owner didn't do with the carb swap.

Also learned the carb has bern trashed during an overhaul by prev. owner... Will be ordering a Weber 33/36 progressive unit....
