Carb Air Mixture Screw Coming Loose

Slug · 10-28-2022, 06:23 PM

I have the Nibbi PE28 on my bike and it was running quite fine at 2 turns out since installing and tinkering with it.

Me being a dumdum decided to try 2.5 to get rid of barely noticeable backfire at idle... Now the screw won't stay where I set it at all.

e.g. set to 2 turns out, ride down the road a mile perfectly fine, come to a stop, and it starts bogging badly, screw is now out 4 - 6 turns.

I don't want to use blue loctite because.. well, it's a brass screw and I'll never get it out again.

Anyone else have a similar issue they were able to resolve?
