Pull the rubber back towards the knob from the peiece threaded into tge carb. Then put a zip tie around the little fingers that grab tge pluger shaft. Tgey just get weak after time and dont grab any more without some help lol

Okay thank you guys hopefully the zip tie idea will fix it if not I'll just order a new one.

The zip tie "fix" will defeat the sealing boot and create a path for dust or water to enter the carb.  :thumbsdn:

I read something about safety wire being better than a ziptie would this be a better option?

If you can get it to work, it might be, but either method should only be used as a stop-gap until a new part can be substituted.
