no blue loctite, rats! - goodbye idle screw...

    was already to set out for a ride. Sunny and the low 60's here in Phoenix today.

    I had noticed from my last ride, (half way into it), my engine wouldn't hold an idle when engaging the clutch. No biggie, I made a mental note to check the idle screw position when I set out for the next ride. Well that was today, and noticed my idle screw was gone. It'd fallen out some point, (no doubt why I couldn't keep an idle from the last ride).

    shame on me. I've been good about using the blue loctite on everything, BUT that idle screw. :dunce: Since I figure I'd be tweaking it from time to time, no need to put anything on there.

    any rate, no ride for today. :icon_cry: Luckly, I found that Dax carries spares! yippee...

    So I bought two, but will use the blue loctite next time....

    my engine is a Grubee Gen II, so I presume the Dax part should fit it just fine?

    That's weird that the idle screw would fall out. Did you have the spring on it? Maybe it was missing?

    An idle adjustment screw is not something I would use loctite on, not even the blue stuff. Maybe stretch the spring on the next one a little to help it stay in there.

    I thought the same thing too. it had the spring on it. Not sure how it could come out either. I really don't want to put loctite on it either. I did buy 2 idle screws from Dax, just in case it happens again. I'll try stretching the spring as well.

    and I only had it set at about 4 turns out (from being closed). so I'm sure there was a fair amount of threads still engaged. bizarre. :goofy:

    Before I'd Loc Tite a carb screw I would do either or both. 1) Stretch spring 2) Take a thin wire, about 6 inches long or longer. Wrap around screw once at the 3 inch mark (mid center). Twist wires together until the end, wrap around something and cut extra off. Should the screw come out the screw won't be lost. This can also be done at one of the coils of the spring. Will not hamper idle adjustment. I use thin stainless wire as a fuel line clamp.

    Thanks Al. I appreciate the input. I'll give that a try. :D

    I like the idea of stretching the spring.

    I used blue loctite on mine (little dab will do ya)
    and I can move it with a screwdriver ok, but not turn with fingers.

    maybe nail polish? I keep reading people saying they use nail polish as a loctite. How strong is it?

    What a bout a wrap of thread seal teflon tape. This should do fine and its not a glue, so it can be safer to your threads.

    Safety wire on idle screw: SMART!

    I like it. I ran out of safety wire, but its good for tying standard bike grips. The throttle grip set with my gurbee didn't need any.

    received the replacement idle screw & spring (via Dax). Fits up just fine, (as expected). But unfortunately can't take the bike out for any test spins. A major winter storm blowing through Arizona, (raining down here in the valley & lots of snow up in the mountains). Will try it hopefully tomorrow. :cool:

    I'm sure it is needless to ask, but you didn't mention if or how you solved the lost screw issue, if in fact you already have.
