2001 optimax rough at idle 500 hrs .hesitates to get on plane for about 2 seconds.Runs at wot fine .new spark plugs and wires to remedy, nothing .Run quick clean regularly every other tank full ,and only use dfi oil forever
#5 spark plug clean with gas on end of spark plug #1 had slight gas but not like #5 all others dry with slight carbon.Battery test's ok .Fuel rail no air coming out during test.Im lost any help would be appreciated
 
Get two fuel pressure gauges, Good ones, and hook one to the fuel rail and one to the air rail. 90 lbs fuel pressure and 80 lbs air pressure.

After you determine the fuel and air is correct, you will need to check the reed valves to see if they are cracked or broken.
