what the hell happened?

An admitted newbie here, bought my first Wrangler last weekend! I've wanted one forever but it was just never in the cards. Finally picked up a 90 YJ safari (immediately removed those ugly stock decals). Ran fine getting it home, bogged down a bit under acceleration. Seller did state it had been sitting almost a year with very little use. PA inspection stickers and od show only 1k Mikes driven. Thought maybe bad gas. Hit the carb (Webber) with some cleaner and it seemed to help. Added some fuel treatment to the tank then wham! The next start up it coughed, backfired and shut down. tried a few more times with varying levels of failure. Now all it does is crank. I'm thinking maybe some gunk broke loose and fouled the plugs. It's been raining like crazy and have no garage so haven't been able to check them yet. It's been almost 10yrs since I owned a vehicle with a carburetor. Anyone have any other thoughts?

I'm thinking it's feelings were hurt!

I would start by changing the fuel filter or at least inspecting it making sure that fuel is making it to the carb.

Bought a new fuel filter before I even got it home, so that's done. And yes, it has a carb. I'm sick of having to check codes. Lots of good it's done so far :/

The float could have muck on it from sitting for so long and the cleaner could have broken loose deposits and clogged that new filter/lines/jets etc.....try changing the filter again and see what happens. You may need to pop the carb off and open it up for a good cleaning.

Before doing that it may be a good troubleshooting step to see if the engine responds to a little starting fluid. If it does that will verify that fuel is the problem. Then move on to why the fuel is not reaching the carb.

A good carb cleaning was gonna be my step after checking the plugs, so thanks for confirming that. Glad to know I was thinking along the right track. It's been a while since I've had to wrench on a primitive engine, realizing how much I've forgotten. It'll take a while but this rig has massive drivable project potential. With only 89k original miles I'm looking forward to years of topless fun

Ditto on that! If it's been sitting for a while, the gas could have varnished up and clogged in the carb somewhere. Sounds like a good carb rebuild is needed.

we went thru the carb twice. First the float setting was way too low like it was never adjusted, but the varnish from sitting plugged the jets and with the metering rods already going thru there is little space to keep fuel going during decelleration. where the varnish is clogging will not be moved with spray cleaner. Our fuel tank was also full of rust so we changed that out and blew out the lines because after the first rebuild of the carb it all worked right back in, even with a second fuel filter installed to clean up.

You pull the top off to see the float bowl and you will probably see a gel all over the bottom.

I'd start w/spark plugs and new cap & rotor.

I know its probably a fuel issue w/old gas but if you replace the cap & rotor plus the spark plugs you'll increase your chances of being able to burn tarnished fuel. Run that tank of gas through it then replace the spark plugs again once you fill it back up.

Just an idea...

Has new cap/rotor & plugs already. Like I said, ran fine getting it home except for bogging down a but under heavy acceleration. Gonna start with what I touched since that's when it crapped out. Remove and clean the carb, change the fuel filter (again), check/change the plugs and def try the starter fluid test. I had forgotten about that simple check. Maybe drop in a k&n air filter while I'm at it just because. Thanks for all the great advise, best forum site I've ever checked out.

start with simple and work towards harder things.

i would definitely verify that it will even run on starter fluid. make sure its a fuel delivery problem before spending more money. i am not a fan of spending money needlessly as a hope for it fixing something.

Been busy as all hell, haven't gotten to the t/r until this evening so here's the update: yes, it fires up IMMEDIATELY on starting fluid. Checked the plugs and they were wet (not sure if it was fuel or starting fluid though). Removed and checked the carb for gelling and it is perfectly clean. Reinstalled and attempted to start it again...nothing. Hit it with starting fluid again and fired right up, briefly. Checked and the float bowl is full...fuel flow, check. Now I'm dumbfounded.

Dumbfounded is how most YJ owners spend our time.

If the float bowl is full and it runs on starter fluid, it's almost gotta be clogged jets.

Hahaha! Either that or bad gas/overabundance of fuel treatment. Gonna drain the tank and get clean fuel. Anyone need any weed killer?

Update: solved the problem. Checked thief float again and found it empty. Replaced the factory fuel filter and installed a clear inline filter before the fuel pump. It fired right up. Ran around the block and it stalled as I pulled back up to my house. Found a bunch of crud in the clear filter. It's my assumption that the fuel treatment knocked all the crud in the tank loose. Replacing the fuel tank and blowing out the lines should cure it. Thanks for all the suggestions!
