Hey "dogman"
I have the ofna primer pump..so what I did was blow into it to see wich direction the air travels through it because that is the direction I want going to the fuel tank if I am correct. I know I have to retune it to compensate for the increase in pressure, I assume that the factory settings on the needle will be to rich, so my question is where would be a good starting point to set the needles. Thanks..![:-]
