Sometimes carbs will leak after bouncing around on their side in a delivery truck.

If leaking ...
1. Before "wacking" turn off the gas valve.
2. Start engine (with gas valve closed) and rev it up several times (most often the vibrations will loosen the float valve needle).

Usually there is enough gas in bowl to rev it up several times.

3. Turn gas valve back on.

Tapping is better than Wacking!

When tapping it is better to tap on the 5/8ths hex head of the drain plug.

That way the paint is not damaged and drain plug can be replaced if dented.
