Fuel Screw? Help

DRZ400e (04)

Installed the JD JETTING. worked as advertised. Removed the off idle bog and helped H.P. The problem began when I removed the stocked fuel screw and repaced it with the ZIP-TY FMS02 fuel screw. The off Idle bog has returned and I have been all the way in and all the way out with little results.

CARB CONF for 1500 ASL: Blue needle #3 162 MJ Pilot and air stock the stock Fuel screw was at 2.5 out. Ran great.

Whats up?


The stock fuel screw has a very small o-ring, flat washer and spring

that has to be installed onto the new Zip-Ty fuel screw, could you have put it in without these ?
