Carb tubes. Where does it lead?

Post by DandruffCat »



I have a vacuum leak that I'm getting around to fixing. I saw talk about the "toothpick trick" and decided to give it a shot to medicate the surging until I had time to work on it. Well, now the bikes all apart to fix the leak, but the toothpicks are jammed. They've been soaked in fuel it seems like and now are very weak and can't be removed in one piece. After my bad attempts to remove them, there's no part of the toothpicks exposed anymore and are jammed inside the tube they're wedged in. My idea now is to get on the other side of the tube and blow compressed air or something similar down it to shoot out the toothpicks.

But, where is that other side at?

My guess is somewhere in the float bowl. I've heard people call this pipe an air vent on the forum.

I believe that is the idle air bleed. You may have luck removing the idle jet and using compressed air there. Or you might just have to carefully use a pin vise and the correct size drill bit.

They are wood soaked in fuel…use a small torch and burn the tooth pick out! :lol:

Pin vise! First time using one and it worked perfect. Thanks for that, saved me a lot of headaches.

I was actually about to do this when I realized there's still fuel in the carbs and it leaks out when I orient it different ways. Close call!
