Weber 34 - choke plate won't open??
I put a new Weber carb (34/34 from Quadratec) on my new Jeep a few months ago. A little while back I noticed that my fuel line was kinked because the fuel inlet barb was all the way on the fender side of the carb. I changed the fittings around to the middle and shortened the hose.
Now, I THINK I readjusted the idle settings on the carb shortly thereafter, but maybe I'm mistaken. Anyway, I had electrical problems for quite a while afterward and couldn't get it started; then once I fixed them, it would start, run for maybe 15 sec, and quit. I thought it was a vacuum leak or something, tightened the carb down and fidgeted with some hoses, but no luck.
I thought maybe it was running too rich (I don't judge smells very well...) I took the air cleaner off and noticed the choke plate was tightly shut, so I propped it open with a screwdriver. She started right up and began to roar, so I figured I'd found the problem. But I can't seem to get the choke plate to open up, no matter how much I adjust the choke pull-out or fast idle screws. I did put a fuel pressure regulator on and turned it down to 2 psi, which seemed to help, but I think I'm just masking a problem. (I also just flooded the beast with Sea Foam...I propped the choke open and got it started again, but...) It used to start choked and revving high, then when I tapped on the accelerator it would fall off. Now tapping the accelerator does nothing. Is there something broken on the carb? What do I look for?
