hey guys, i was seeing if you could help me out with a problem that has me at my wits end.
I am working on a 1996 arctic cat jag 440
twin cylinder, air cooler, single carb, two stroke
This sled uses a vm34 mikuni carb with an enrichment circuit for its choke.
so the problem i have is that the sled is super sluggish down low, in fact a lot of times it will die if you only give it part throttle. this lead me to believe that the pilot circuit was plugged up. I have pulled this carb apart nearly a dozen times and have cleaned the fuck out of it. I have chem dipped it, boiled it, carb clean, and blew compressed air into every port/orifice. i dont believe it is plugged up anywhere because i get good air flow through the corresponding holes. the intake boot is also in good condition without any cracks.
No matter what i do, the sled still acts the same. absolutely no power down low but runs just fine at wide open throttle. i have tried adjusting the air screw but that doesnt seem to change anything either. i just dont know where to go next.
does anyone have any suggestions? the jetting is factory for what the sled should be, 300 on the main jet and 30 on the pilot.
