I just got done updating my 600's carb with the new jets and spring...etc as per the latest polaris bulletin for the sp twins,
and I gotta tell ya, it's a whole different machine!!! this thing never idled right or started well when cold, had to use so much
choke! even in warm weather it would pop/backfire if you tried to take off with out warming it up a few minutes... and off and
on just plain ol ran like crap! I still need to fine tune the low speed mixture screw per the bulletin (it is too cold out now) but
it starts right up, only have to pull the choke out about 1/4 inch (40 deg's out), give it a couple bursts of throttle, turn off
the choke and go! just purrs like a lion!!! now I might actually use it for hunting this year!!! last year i didn't bother, because I
didn't want to leave the extra 1/2 hour earlier that it would have takin for this thing to warm up so it would run! seems a
little snappier with the new Dalton clutch springs also...but we will find out for sure when the weather gets nicer and
things dry out!!! can't wait to hit the trails!!!
