Half Choke Idle?

[redhatman]

It seems as though my blaster will idle PERFECT at half choke, but I have heard it is bad to run at half choke.

I am running 32:1 92 octane, valvoline 2 stroke with an idle kit, .010 over wiseco piston, stock air filter. Boyeson Superstock reeds.

If I push the choke all the way in it seems to idle too high like it is lean, yet when I run it at half choke it seems rich for 0- half throttle.

I am heading to spider lake in a few days and would like to have my atv in tip top shape.

Is there anything wrong with running half choke all the time?

Any suggestions for fixing this?

Sounds like you may need to rejet, but first, get a new spark plug NGK BR8ES, and Use the below link to help you diagnose if you have a jetting problem or if you are running ok.

try turning your air screw in a bit. start by turning it in all the way to a light seat, counting the turns as you go. then as long as it was originally out further than 1 full turn, just turn it out less than it started out as.
this will richen up your idle circuit. then you might also have to fine tune your idle screw as well. once she sounds like she's idling good. put in a new spark plug and let her idle to warm w/ the new plug and see what it tells you.
