I have boiled carburetors in hot water for 1/2 hr and sometimes that worked for me. If its internal and it cant be reach with high air pressure then you have to soften it up some and hope it either dissolves or melts apart. Think me crazy if you like but sometimes disperate things require disparate actions. Lol

Always fighting the ⏰ never enough time! Story of my life, I finally got around to the Mojave I picked up almost a year ago. I have my two boys washing it down and getting it ready for a tear down. Looks completely in tact, the original tool kit and paperwork was in the rear compartment! Hoping this thing only needs a carburetor cleaning and some fresh fuel and spark plug. Pulling all the stickers that are on it except for the factory ones since they are in great shape. In a few weeks she will be like new, just not sure what the heck I’m going to do with it.

Thanks guys! Now if I actually had some free time to work on the bike. Hopefully I'll get a chance to look at it this coming weekend.

Agreed, we need more information about the machine before we can make suggestions. Mike

16.5 volts is too high, that would be the regulator going bad. A quick test is when its not running right to turn on all your headlights, if it runs better, it is voltage related. Should not run more then 14.5 volts , service manual can be found here: https://www.mymowerparts.com/pdf/Arctic-Cat-ATV-Repair-and-Service-Manuals/Arctic-Cat-2003-ATV-Service-Manual/ Schematics are here: https://www.mymowerparts.com/pdf/Arctic-Cat-ATV-Repair-and-Service-Manuals/arctic_cat_2000_thru_2009_atv_and_snowmobileSnow_Wiring_Diagrams__NOTE_LARGE_FILE_459mb.pdf A good online place to order parts is here: https://www.countrycat.com// Mike

Thanks for adding the manual Spartacus, I’ll keep an eye out for it. I just got a used oem carb yesterday. Once I get a chance to check it over I’ll put it on and see what happens.

Have you checked timing? Or for a bad flywheel keyway?
