Hi y'all. I have a tank mount 3hp briggs with a pulsajet carb. I am trying to get it to run and am waiting on a new diaphragm to come in the mail.
Is the sole purpose of the diaphragm to pump fuel from the large tank to the smaller well within the fuel tank?
I ask because I can't get my motor to start. Under the assumption that my diaphragm is bad figured I could bypass it by filling the smaller well within the tank thus allowing me to start my engine and see if the diaphragm is in fact the problem. Now I am wondering if the diaphragm also has a second function of somehow creating vacuum for the shorter pickup tub that brings fuel to the needle valve? Anyways thanks for the help, any info is much appreciated.
