It only happens when it is warm out (75*). When it's cold out it's fine (45*). After 3-4 cranks it is ok...still a little sputtery but not stalling. Idle looks to be about 800-900 when its warm. Is there something I can adjust? it's stick. I do not know what specific weber it is. It was on when I bought it. I had a fuel pressure regulator on but removed it as I didn't know I needed it. If that is related please advise.

You do need the pressure regulator.
Don't know if that will fix your problems though.
I think its supposed to be set to 5-6'ish psi on the regulator.
Someone else could probably give you something more precise on that.
Good luck.

Ok thanks! I thought I read something like 3 1/2? Has pressure from filler hose when I go to pump gas. I presume this is related.

Yeah I googled it and weber says 3-1/2 psi recommended.
I don't have the sheet near me but some install guide I had says that 5 worked for them fine.
I guess you should install it and try 3-1/2 first and see if it helps.

Just installed the webber, but will not run with the regulator... tried it several different times and runs great without it..... Pretty impressed with the webber as it has much more top end power. I have heard so many mixed reviews about regulators and for me works best without it.... weird.

I ended up leaving the regulator off. It needed to be adjusted as it got warm out. I adjusted the timing. Runs like a dream now.
