Webers-need fuel pressure regulator?


I've just put a pair of webers on my buggy and it's running horrible. It has the standard fuel pump so I didn't put in a fuel pressure regulator. Could this be my issue?
Both my other cars running webers have a regulator but are running electric pumps. It doesn't appear to be running rich. It's a new engine 1641, runs ok with the revs up but hard to take off. Ideas?

Barls runs a pressure regulator on his 2 litre with twin webers and i know that it ran like s...t with too much pressure, apparently they use a lower pressure but I can't remember the figure, I am sure that he wll let you know what he is running.

I have not seen stock pumps put out greater than 3 lbs

Are they Webers or something else.

What is your jetting?
Mixtures set properly

What is it doing wrong

Yes 40mm idf webers. I'm going to put a pressure regulator on it. It doesn't seem to be overfueled but it's running like crap down low.

Ive been using a stock VW mechanical pump with my 48 IDA Weber street beetle for over 40 years with no regulator. If the (unlikely) pressure is too great, add a few gaskets under the mechanical pump. Depending on the size of the needle and seat (most common is 2.0mm), a fuel pressure of 2.5 lbs is adequate.
Sounds more like a tuning problem rather than fuel pressure.

44's on a 1641 are on the larger side. Putting in a smaller venturi (choke) will improve low end response.
Every carb works well if you rev it but it is down low and on transition that is the tuning area
