Hi,

I think the vacuum petcock is one of the greatest things since sliced bread. But some here have done away with them and installed a generic Pingel petcock. You may or may not require an adapter plate. You will have to cap the vacuum port on the carb. And you will ALWAYS have to remember to turn off the gas when you stop the engine.

And before you ask, see z1enterprises.com for your Pingel.

Thank you for your indulgence,

I suggest testing the petcock before assuming too much. Clear tubing for the vacuum line will tell the story.
