Question

My fuel screw needs to be turned out around 4 or 5 turns. It almost feels like it is going to fall out. Also it is starting hard when its cold. Is this an indication that my pilot jet needs to be changed. If so, what is the stock pilot jet and what do you recommend I change it to? Thanks, D :):D :D

Means you need a couple size smaller pilot jet....more than 2 turns out you're too rich, less than 1 turn out you're too lean.

Ill-caper,

At 4 turns out the FS will fall out very easily. Stock PJ on a 450 is a 42 or 45 I think. Either one of those should not need 4 turns. The JD kit is designed to work well with stock PJ and 1 1/2 to 2 turns on FS. You may want to give the carb a good cleaning.

youve got it backwards.its a fuel screw on a four stroke.it needs a bigger pilot or a needle with a richer/smaller starting/straight demension.

45pj is stock. :) If the 170mj and JD needle are working for you(considerably richer than stock setting), I would think you might need a richer pilot as well. 48 maybe?

I have a 48 in mine and it seems to work well. I am at a foot and a half above sealevel.

Use a 72 starter jet for the winter. It helps with cold starting. :)
