Have a 140G blade with a 3306 in it. Fuel pressure was all over the place previously, thought I had her nailed with a leaking fuel priming pump. Few days later she won't start back up after lunch. No fuel pressure at all. Got it figured out and started and running again. My fuel pressure is on the higher end of spec for high idle at 31 psi. But low idle sinks all the way down to 16 psi. Operator has no complaints of low power or dying out. But it bothers me a little. Anyone know low idle pressure spec or have a 3306 that can tell me their low idle pressure???
