Well I pulled the fuel bowls off to double check what jets were on it & put on a set of jet extensions on it. Buttoned it back up & the rear floats hung open...Messed with the adjustment & nothing. pulled the extensions back off & it worked fine. What is going on??? are there different length jet extensions???

It's a dommmy 1150 & the fuel floats are notched, Do the 1150's come with jet extensions???? I really don't know where the extensions came from because the were in the box when I got it back from the dyno testing???

A friend mentioned he had a similar problem once & eneded up ordering the jet ext & floats as a package

The float should black nitrophyl and have to round notch's cutout in the bottom of it, and the angle to clear the acc pump well valve. If its brass its wrong.

What type jet extensions, screw in or press on and which floats do you have now?

I have no idea what brand they are..they are a screw in type & the float is the black plastic with the notches cut or formed in.

Are their different lengths of extensions that wouldnt work with mismatched floats??

I had that problem before,and filling the bowls slowly by turning the pump on and off repeatedly fixed the float from sticking.

mine stuck as well--its the brass screw in ones. i just cut a bit of length off them till they would not hit the float.
works great now
