It does have an electric pump and pressure is set to 3.5psi. I'm gonna hook up a return line to that second port on the carb and drop fuel pressure down to 3psi and hopefully i get better gas mileage that way. It got about 15mpg on the highway with it so far. It has a slight miss at idle which i think is due to being too rich, but driving it does just fine.

One other question. Is the idle mixture screw just to get the idle smooth or does it effect the entire operating range of the engine?
