Ticking

[Sean]

The last couple of times out on the boat I've noticed a ticking sounds comming from the engine. Today why sitting @ the mooring I decided to investagate a ltile further ::)
I noticed @ ideal that the noise seem to be comming from the gas line, enchoing in the ball?? I took the cover off and the line seems to be less eratic in the motor itself? It also seems to stop once the engine is reving @ a higher RPM
So, whats wrong ;Dand how do I fix it ;D ;D
