OK, neighbor gave me a nice Honda 5.5hp pressure washer after he bought a new one. This one has sat for a few years and was not running. After draining fuel, taking apart carb, cleaning, new plug, etc. It will crank up and run instantly at all throttle speeds unless I have the hose hooked up. If any kind of load is applied it will stall and then i noticed it will only run with thte choke blade almost closed. As soon as you try to move it to the wide open postition, no matter the engine speed, it will spit and pop and backfire and stall.
I was thinking carb issuse, but it is clean and i ran small wire through all the jets, etc, i know they are clean. So then Im thinking ignition problem for the backfiring, but that wouldnt make the lean condition.

Anyone?
