Welcome to GTT!
just a thought here...........I have noticed that if I pull up on the PTO switch ( X590) to restart the deck blades, sometimes at Idle speed I get nothing but when I do it at Full Throttle it starts right up. Is it possible that you are experiencing a similar issue? Can you increase your engine speed and see if that resolves the issue? It might be a RMP/voltage relationship!Will be back on the this issue this weekend. New fuel filter today and will check battery voltage also. Just wanted to bump this up and hopefully get some new eyes to see it
Thanks George
12.1 is a bit low for a fully charged battery. What does it drop to when cranking or when the PTO switch is engaged?Still poping and stalling bad when under a load. New fuel filter and fuel lines are clean. Battery voltage is 12.1 when engine is off and 13.5 while running. Gas tank and fuel lines are clear and clean. There is no filter inside of tank so thats not it either. Got an OEM fuel pump coming. Could this have anything to do with the electronic PTO. Iam really hoping its the fuel pump.
