Hard starting with weber?

The new weber is a fantastic improvement for my jeep, its like a new vehicle. The onle complaint I have is that it takes about 20-30 seconds of cranking to start if it sits for a couple of hours. I did a search on this and found it is a common problem, but I didn't find any solutions. I was wondering if a electric fuel pump would help and if so has anyone else installed one. Any ideas or advice appreciated.
Thanks

Most of us just live with the little annoyance. IMO, an electric pump would probably help, but why bother!?

Re: Hard starting with weber?

<font face="Comic Sans MS">I tend to look at it this way, when it's not starting for those 20-30 seconds, it gives your oil pressure a chance to come up and everything gets oil before the added stress of the engine actually firing up. Might help add (at least a little bit of) longevity to the engine because of that... </font>

Re: Hard starting with weber?

I have the exact same problem.
On thing I noticed is: Instead of cranking nearly continuous for 30 seconds, it seems to help to crank it for like 8 seconds... Sit for a few beats, and then go.

I'd love to hear a good solution, just because its a little embarresing to have to crank your truck a couple times.
(my thinking is that after all the time I put into improving my YJ, its a shame my roommate's neglected Civic starts better)

One other note: Mine seems to be cold-related and isn't nearly as bad when its warm out.

Re: Hard starting with weber?

I have to pump the gas 6-8 times then 5 seconds of cranking it starts up. The weber does not cold weather.

Re: Hard starting with weber?

Wow, that is great news...

My newly installed Weber does the exact same thing. I thought I was going to have to fix it. What a relief, one less thing on the CJ that needs fixing.LOL

Re: Hard starting with weber?

I pump the crap out of my $10 weber 32/36 and it starts as soon as I hit the key, 75% of the time . Can`t beat it!

Re: Hard starting with weber?

I have an Edelbrock/Weber 4 barrel. After it sits for a while, the gas drains out of the bowl. I can either pump the gas 6 or 7 times or I can drain the batteries. After 6 or 7 pumps, it cranks right up.

Re: Hard starting with weber?

My Weber 38 does the same thing, it sure is a commen problem. I have had it on my Jeep for over 10 years, but it seems to be getting worse over time.
The first thing to check with this problem is that you have the correct 3 port fuel filter installed, with the off set return line positioned at the top of the filter.
Also, some have suggested that the fuel pump might be worn or internally leaking/bypassing and allowing fuel to drain back to the tank. I bought one for $12.00 from the local parts store, but haven't had time to swap it out yet to see if this fixes the problem.
Finally, another solution would be to install a one way check valve somewhere in the fuel supply line to absolutely prevent fuel from draining from the line. If the new pump doesn't cure the problem, that's my next step.

Thanks to everybody who replied. It's reassuring to know that it is a common problem and not just me.
