I have heard that doing away/by passing the TVS is the way to go on these coaches.

So what is the "proper" way to plumb these vacuum lines when doing so?

There are 3 ports on the switch ( carb, vacuum advance, and tee line that goes to manifold and trans ).

If I run the spark advance directly to the ported spark port on the carb, I am left with an open port on the switch.

Per the manual, the TVS allows vacuum advance after the engine has reached operating temp.

And if anyone knows what the other ports do, I'd appreciate the knowledge.
