At the beginning of the summer I wanted to rebuild my carbs (72 CB750).
To make a long story short when I put the carbs back on I ran the fuel lines under the bowls.
all summer I've been chasing a leaking gas problem. It was driving me CRAZY.
Then I realized that before the carb rebuild my fuel lines where ran above the bowls through the two holes.
Not a drop of leaking fuel so far.
Anybody else have this problem.........Sure was frustrating
