weber carb issues
 
I just put on the weber 34 dgec last night hoping to solve some problems on my friends jeep.

Before, it had a remanufactured carter carb and it had got to where it was running really rich and was very weak.

After putting the weber on, the engine is running much stronger but we are having trouble with the idle speed. Sometimes it wants to idle high but most of the time it idles so low that it wants to die.

Also it's still puffing black smoke at low rpm. I haven't made any adjustments to the carb because the idle speed is not consistent. I'm going to check for vacuum leaks today but do you guys have any ideas?

The only things we have attatched to the new carb is fuel, vacuum advance, throttle cable, pcv valve, and valve cover vent to the breather. I didn't see anywhere to attatch the other vacuum lines so we capped them off according to the instructions.

Also, my friend said that the battery gauge is reading much lower now. I have no idea how changing the carb could effect that but i thought i'd toss it in there anyway...

Did you hook up the electic choke control? Are the plugs, wires, cap, rotor all good?

I`m saving up to buy a webber also I read that you may need a fuel regulator it was printed in the Quadratec summer edition that what I read Idont know anything about carburetors.

I certainly agree with drox. Your advice is really very helpful for us.

I have the same carb. I have all smog stuff removed put in the nutter bypass and is better now. Changed the jets on outside of carb to 47.5 primary and 40 secondary. It idles great can idle at 600-700 no problem but going down road it runs out of power. I don't have reg. hooked up yet. The paper says hook up vac . advance to carb base but on mine when I do that the advance goes full at idle. Where do you have youres hooked to. Everyone says you need ported vacuum and I can't find anywhere to get ported vacuum. Let me know how you make out.
