Bench testing carbs for gas leaks

Postby twocams » Fri Nov 20, 2015 4:46 pm



After rebuilding my Wing carbs I thought I would make sure the float and new needles were working. And no leaks from the 24 "O" rings that were replaced. Thats including the float bowls. I used some clear gas tubing from a local bike shop so I could see when they were full. Used a big syringe (usually) for cows and horses and fill with gas. When the gas stayed in the clear tube both carbs were full. Let it sit for a few min. then pulled the drain plugs. Did the same for the other 2 carbs. And wola no gas leaks. :shock:
Test out!!

no leaks is always good...I used a spare fuel pump when I did mine, regardless how you do it, pre checking is a smart move

Ya fuel pump test would be nice. But after setting for 5 yrs with gas in it not sure if it even works. Then I would have to take the battery out of my BMW to test it. So this was just a quick and dirty test. :) Lots of work to do yet....slow but study.
