Hi, my sportsman 400 runs fine spring summer an fall, but the winter is a killer, if it doesn't warm up for like 25 minutes it stalls whenever I go into reverse, hi/lo forward seems to be Ok I think (I can't really remember) I adjusted the etc to 1/8" and I bumped up the idle so when I change gears the bike actually jumps a bit (too much idle maybe) is it a carb issue, and I changed the plug, and load tested the battery (fine) it seems temperature related, also I broke off the hi/reverse shift linkage bar b/c it was really hard to shift (probably related to the hi idle rpm??)

 

Turn the idle mixture screw out 1/4 to 1/2 turn and that should help.

 

I'll try it, but first how can I identify which one it is?
Will I have to turn it back in after the winter?

Thanks so much

Hope this works as a link, looks like part 26 is the idle mixture screw. It might have a
brass plug over it that you have to drill a small hole in and use a sheet metal screw
to pull it out.

 

ditto on the air fuel screw, should be 2 to 2.5 turns out, I have seen them completely shut from the factory, its on the bottom of the carb and probably does have a brass plug over it.

 

Thank You for the Parts Manual and the info. on the carb.
My 400 Sport does`nt like to idle too good in colder weather too but I now know where to go to get it adjusted.
Whenever I get a new or new to Me machine I usually get the parts and repair manual too.
Is there someplace to get the repair manual for free like this parts manual?

OOOPPPSSS I just looked at the thread and this is for the 02,Are they the same as the 05?

you can get this on polaris website. Just set up an account and then you can download any parts manual.

 

Thank You very Much.
I tried to change the parts to repair but it came up with page could not be found.LOL
I will order the repair manual.
I am surprised that these engines have rockers with adjusters instead of shims.That will make valve adjustments much easier.Sorry,did`nt mean to hijack this thread.[img]i/expressions/face-icon-small-happy.gif[/img]
