I made all the modifications to the crank case that were in the instructions with the polini reed valve kit, including the removal of the rotary pad and matching the manifold to the case... Power at the low rpm would be very helpful right now, I will try advancing the ignition when I get some smaller jets.

Thank you for the information! The carburetor and fuel tap are new. The fuel line is pretty straight. I think over jetting could be the biggest part of the problem. That is what i will try to fix next. It has an electronic ignition from an et3 and I have the ignition set at exactly 16 degrees before top center. I exchanged the dellorto with a mikuni from my friend's et3 and it was a little better but still not good. It worked ok at the top of the gears.

Hi,I live in Boston and I just rebuilt my 1974 vespa primavera motor with a polini 130 kit, polini reed valve conversion, and a dellorto 24 phbl24as carburetor. It has a 100 main jet, a 60 starter jet, and a 50 idle jet. I did not cut the crank because of the reed valve installation. I made all of the reed-valve kit alterations recommend by polini. It starts right up and idles well, revs well in neutral, but dies when I try to accelerate. I have been told this is the most knowledgeable scooter forum out there. Does anybody have an idea about what could be wrong? Danke!
