Weber ?

I have a weber 32/36 carb abotu a year old, one thing I noticed is it takes for ever to start after it sits for a couple days, I've adjusted the choke and thats working fine, I am thinking that the fuel is either evaporating from the somehow draining. any ideas?

besides the 83 cj-7, also have an 87 yj, 6cyl., 5spd, weber upgrade, 6.5' western uni mount plow, also a 2000 Sahara, 4.0, 5 spd

Mine did the same thing. It would start up great if you drove it at least once a day- let it sit for more than 2 or 3 days and it'd take you a lot of cranking to get it to fire up.

The best I could figure out was the fuel drains back down into the tank while its sitting. I pulled a fuel line back by the tank and there was no fuel in the line.. SO- that was my best guess. I never bothered to fix it. The only thing I could think of doing would be to put a one way valve in the fuel line right before the carb to keep some of the fuel in the bowel, but that may not work if it's evaporating out of the bowel.

I've seen a lot of people with Webers with this issue. Most people seem to think along the lines of what MetZenDS said, fuel run out of the line (many seem to blame it on the return line from the fuel filter Being lower than the feed line to the carb). I have never had a problem, a good pump and it starts quick, even after a couple days, so I don't know what more to tell you.

hmmm weird I have kinda the oppisite problem, mine fires right up but if I let it sit say at the mall or something for a couple hours and try it again it has a hard time, after a couple of days I give it 2 pumps and it fires instantly.
Started with some rust repairs ended in a SOA...
