Weber carb on a 4.2 258
 
I've got a weber carb on a 4.2 258 no return line.
I added a fuel presser regulater. Who runs this and what should I set it for onroad? and off road.

I believe it is 3 lbs. I will check mine tomorrow and try get back with you. You can also go to Webers website. I think they will tell you too.

I just worked on one today with a return line. We set the pressure to the carb from 7 to 3 psi and then adjusted the needles and it runs sweet.

great, I got a reply from weber and they say to set the fuel regulater at 2.5 onroad and 1.5 offroad.

I've been out Jeeping and works great at 1.5 offroad on the hills.
So much better.
