RE: Saito 180 with perry pump
I have ran a 2 tanks with the stock muffler on a test stand and it was running good. Not until I hooked up to the pump system did I get the problems.. I have tapped and fitted a nipple in the exhaust and took off the vent. So tomarrow I will see how it runs at the field and with luck get to take up the hawk for the first time..
