Ok I decided to remove the choke of the 400EX so I ordered a 42 pilot jet like everyone said to do. Well I thought I knew what I was doing and pulled off the bottom of the carb and tryed to put in the Jet first WELL I figured couldent find where this things sposta go I had springs FLYING and I was wondering if it was gonna get back together, well it did but I still what to replace the jet I ordered it from marcums on the recept it says #42 SERIES 22 PILOT JET is this the one I need? They charged me $3.80 for it.

Wellll....... the series 22 is the wrong one, i think... You need a series 21.

There is also a very good thread in the FAQ forum by Zingnut, titled "Instructions on changing your pilot jet (cures cold starting blues)"

after you change jets, how many turns out do you set the air screw?
