Idle adjustment screw

[NIPPON]

The screw in the 1/4 tube was backed out so far that I came out. Where do I screw it back? I purchased this 1995 GL1500A and alot of hissing from the carburetor. Other than this, the Honda is fine.

I looked and don't have a picture of this, and nor could I find a picture of it anywhere in a service manual or on the Internet.

Basically it's a long rubber tube with a screw at the end, and that replaces the idle adjustment screw normally found on a carburetor:

If you have backed it out all the way, you've likely lost the spring and washer that provide tension to keep it from moving.

When reinstalling it, you will be looking for the bellcrank on the throttle, where the two throttle cables connect. On other bikes, there is a screw that is pushed through a spring, and then screwed into a throttle stop. The bellcrank rotates back when you close the throttle until it contacts this screw. That screw limits how far closed the bellcrank can go:

You'll be looking for the stop where the idle screw normally goes - you will put the washer over the end of the screw, followed by the spring. You then screw it into the throttle stop. On the GL1500, sitting on the bike looking at the back of the carburetors, the bellcrank is on the back of the left carburetor, and the idle adjuster screws in from the right side.

If you didn't pull the cable back the washer and spring might still be on the threads, but you're going to play hell trying to get the threads started while the carbs are on the bike. You might get lucky, though. Once, I forgot to install it before installing the accelerator pump and even with the carbs in hand, it was still a bitch to get the threads to catch because of the angle.

Thanks. I found it, and you are absolutely correct. Lining the screw up is is like stacking ball bearings. I will work at it though. Again thank you Goldwing administration.

I applied petroleum jelly inside the threaded hole, and the cable screw screwed in without a problem.

Great! Normally I would advise against lubricating an idle set screw, as you don't want it loose and moving on its own - however on the GL1500, it has that long rubber piece that it would also have to turn, so it should be just fine.

Hey Guys, I know this is an old post, but I wanted to say thanks anyway.
I inherited my Dad's Goldwing last year. It's in really great shape with very low miles and that's the problem. Lack of use has left me lots of gunk everywhere. I say all that just to add some color. This post saved me from completely disassembling the carb after thinking I broke the idle adjustment screw cable. I thought I broke it by tightening it too much. I in fact unscrewed it too much while tinkering and it came out. After a partial disassembly, I was able to push the end of the cable while tightening it and it grabbed the thread and went right back in place!
So thanks so much for the comments!
