Mikuni Carb Stuck Choke

Postby JerrryR » Tue Jan 07, 2020 9:17 pm

Hi All,
Please forgive me for posting something non bike but I need help and you guys seemed like the folks to ask. My Polaris snowmobile Mikuni carbs have stuck chokes on both carbs and I'm at a loss to free them up other than by getting out the bigger hammer. I'm not terrible familiar with these Mikunis but from what I can tell the little "barrel " at the end of the cable and spring should just pull up and out, it won't. I've been soaking it with PB Blaster all day to no avail. Any ideas?

Hello Jerry, try directing some heat onto housing around choke plunger. Use a heat gun or similar (no flame). These plunger type chokes are are beggars for gawling the cylinder and slide. A generous dose of Kroil might help. Also the knob end of the cable can foul the whole show. If all else fails, beer is your friend - then repeat. Cheers Hayley.
