Sorry folks my computer decided to post on its own. My question is this. I just put a weber 32/36 carb on my jeep and now it won't start. I have fuel at the carb but not in the carb. I can spray starter fluid in the carb and it will fire instantly but wont keep running. Any suggestions as to what to check on the carb? Thanks all.

Is this the first start attempt ... how did you determine that there is no gas in the bowl?

It is the first start attempt. Tried for about 30 min. I didn't check the bowl but the fuel line up to the inlet. There is fuel there so that eliminated the filter and pump. It will start easily with starter fluid so the spark is OK. I didn't what to start taking things apart without knowing what I was doing so I naturally came here to get advise.

So when you manually pump the throttle at the carb, no gas shoots from the jets inside the carb?

If i were mine, I would sharply 'rap' the carb bowl with a plastic screwdriver handle while someone cranked the engine. That should unseat a stuck float. If the carb is new though, I would check the fuel pressure you are getting at the carb, should be enough to shove it's way through.

You can grind away until the bowl fills or add fuel into the bowl through the bowl vent, that partitioned set of holes in the cover that are just ahead of the throats.

Seeing as how we haven't a clue how much fuel may have entered thus far, I suggest you add one ounce, thats about 3/4 oz shy of a full DGV bowl.
A clean squirt nozzle bottle is ideal to ring the hole or simply a real steady slow flow so to avoid spills into them.

That should allow it to fire up,... allow it to idle so that the bowl will either continue to fill and or allow time to burn off any added excess fuel in the bowl.

Although both of the longer slots will reach the same destination aim primarily thru that one that is farthest from the throats, it will flush through much quicker than the other.

Correct, no fuel coming out of the jets. The inside of the throat is bone dry. Thanks for the input, I will give the and squirt a try tomorrow and see what happens.

Took a while to get back to this...work got in the way. I found the problem with the no-start. The "new" fuel pressure regulator was not letting any fuel through. Took it off and put the line straight to the carb and it cranked right up....and ran like $^*@. I replaced the manifold gasket at the same time as the carb as it had a crack in it. All seemed well, no warpage, etc. When I finally got it started, it is like the engine is over pressuring. I have oil blowing out around the oil pan, the dip stick, and the main seal. What the hell? Anyone have any suggestions? I am stumped as to why this suddenly started happening. The gasket is correct and all the outlets are open. The new carb doesn't have all the vac hookups as the carter. Could this have anything to do with this? HELP!

I have a Weber

I have a Weber just like yours. I don't know if you did this, but my dad told me that I have to literally pour some gas down the carb, as if I were out of gas. Fired up, ran like crap, but all it took was some adjusting, and now it's running fine.

Dont run the engine anymore but was it running smooth or missing the last time you ran it? You can pull all the plugs and coil wire and run a compression test. The preferred test with symptoms this bad is a cylinder leak down test with a $30 kit from Harbor Freight. This doesn't require you to turn the engine over.
You are pressurizing the crankcase. Usually not a good symptom. You may have exhaust gases entering your crankcase . In any case treat it as a major problem and don't run the engine anymore until you find the source of the problem. Check oil for color change, pull plugs and look for fluids in cylinder and fouled plugs. Don't want to scare you but the symptoms you describe require special testing to make sure more damage isn't done. Really bad piston rings and blocked crankcase vents on valve covers can cause similar symptoms .
