Ok, so one key thing is to keep the pressure at 3 psi or less. 2.5 psi is ideal.
It will run pig rich otherwise because it floods the bowls. Probably part of your
problem here. Don't use a cheapo Mr. Gasket dial type regulator either, they
restrict the flow too much. Speaking of flow, even tho its a low pressure (2.5 psi)
the carb needs at least a 45gph flow rate. The stock fuel pump won't do that
even tho it does put out about 2.5 psi. Not sure what your using.

Heres a site that can help you with it www.gruntled.com/Dellorto.
Go thru that site an learn all it tells you.
