Weber carbs bogging
I've got a 2ltr zetec on twin weber 45 carbs, it runs fine at idle, starts fine, however if u blip the throttle hard the carbs seem to bog down almost to the point the car cuts out, however if u rev it with light throttle it revs up fine, no problem atall, just under hard throttle it bogs and almost dies, any ideas? Thanks.

I bought the carbs brand new and they were setup and jetted for a 2 litre zetec, bolted them on there and it ran fine, just when u give it the hard throttle it bogs down and almost dies, I haven't had them balanced since they have been on the car so possibly could be a balancing issue.

I'm using a facet low pressure pump rated from 2 - 5 psi, and I'm using an adjustable pressure regulator set at 2.5 psi, I can't see or hear any air leaks anywhere, just have to get them properly balanced and see how it gets on, they are the later dcoe carbs with the 5 progression holes to eliminate the dreaded flat spot on the zetec's.

Do I need to adjust the fuel pressure abit then? The regulator dial goes from 1 - 5 psi, I was told 2.5 psi is enough but I'm not 100% sure?
