New bike, need help with these hose?

[cthor10]

I just picked up a 1971 Honda CL350 and had it running for a bit until i noticed that this little hose was leaking gas. Im new to this whole scene so hopefully you guys can help me out. Its a clear tube from under the carburetor that is not connected anywhere. Below is a picture.

if we try to plug the hose up itll leak from a pin on the side of the carb. Where my finger is down below.

Any help would be great guys.

Thanks

That hose is meant to deal with any overflow from the carbs. The carbs will overflow if the float heights are not set correctly and/or if the float needle is having trouble sealing.

For the float height issue, that's an easy fix; adjust the height accordingly.

For the float needle, ensure the carbs are clean and free of all dirt and debris. The float seat should be spotless as well. The needle, if rubber-tipped, may need to be replaced.

Carb overflow hose. Float is probably stuck. At least that what it was on mine.

You'll want to clean those carbs really well and replace all the rubber seals and o-rings. As others said, but float needle or the float itself is stuck. If fuel is leaking out other places when you plugged the overflow tube, you have other leaks in the carbs. You'll hope that too, otherwise fuel leaked into your cylinders and is now in your oil. Check that and make sure it doesn't smell like gas before you start it up.

My float was leaking pretty bad cuz the needle wasn't sitting right. Just took 'em apart, really think I just took off the bowl. Didn't need to get into the main carb at all. Looked over the parts to the float assembly and after a little air blown around the needle sat just fine, no leak. bits of dirt/rust was all.
