Losing prime

im no expert but it sounds like the fuel pump is sucking air from somewhere i would put a fuel pressure gauge and check fuel pressure
could be a seal on the fuel system from the tank to the fuel pump not sealing not sure if your tank has a screen on the fuel pick up and sometimes when replacing fuel fiters dirt can get in the fuel line check the fuel pump may have dirt in the one way valves

Process of elimination, run it off a portable tank as posted, disconnect it from the top of the current fuel tank. Connect this hose to the portable tank if all is well its the fuel pickup strainer in the tank or the anti siphon valve on top of the tank.
You mentioned 60:1 mix it should be 50:1 Typo?
You ran this motor perfectly before so I don't this its anything to do with the disconnecting the vro ...
Be careful not to run it at WOT with a fuel starvation you will blow the power head ...

awthacker, please refresh my memory.
I had it in my mind you had cleaned the tank, replaced the fill hose and the fuel lines to the motor and added the water separator prior to or during your repower.

There was a thread a couple of years ago when Hammer had this same problem.

His ball would get soft and he'd have lefty squeeze it and it would get hard again. LOL!!

Where's old Hammer been? I miss him.

Cleaned the tank, replaced the fuel lines, left the primer bulb because it looked new, did not replace the fill hose or air vent hose, replaced water seperator.
