Smile Choke Adjustment

Having trouble starting a 1999 Magnum Polaris, replaced Choke cable this past season. (Colder weather now) Was wondering if the choke needs adjustment. What is the best way to adjust and knowing it is correct?
Thanks for the help,

The choke is just an enrichener circuit in the carb , if it wont start when its cold out you need to take the top off the carb and richen the needle a notch, take the main jet needle out and move the clip down one notch, this will give it more gas so it will start, also pilot jet screw needs adjusted to 2.5 turns out. Probably a brass cap over it on bottom of carb that needs drilled out and removed.

the enrichern is basicly set so it bottoms out in the seart to seal off the circuit. when you apply the choke, it opens up the plunger and lets more gas in to aide in start up and warm up. most likely there should be a little play in the choke when it's set right. imo

The choke lever seems like there is no tension on it. should I just tighten up the cable so it feels like its has more tension on it?

Follow the cable to the carb then check if its operating correctly then change spark plugs then check restriction inside the air filter then load test battery (might be turning over to slow) then report back here

Question

Checked cable and made some adjustment on the tension seems better. Checked the battery, it was low and now in process of charging. There is another question I have, I did pull the the pull cord and seeing we always start it by the electric starter. It is very/ or impossible to pull, is there a way to loosen this?
Thanks,

you can tighten the grommet just ahead of the choke handle ,which puts a squeeze on the handle,making the choke handle FEEL tighter or looser whichever you prefer.
on compression stroke the ropes are hard to pull, not like the lawn mower when you're pulling out instead of up,unless the got tangled up somehow.

Thumbs up

We got it started, choke works good. Probably going to take apart the pull coil cause it just doesn't pull easy at all. Going riding tommorow, then will work on it.
