Ported vacuum switch
Anybody know if the blue two port ported vacuum switch is open or closed at full temp (130*)?

I went out to check mine, and apparently i need to replace it because i get no vacuum cold or normal running temp, lol.
But, i would assume it opens at 130, because it would pull vacuum through the charcoal canister, from the gas tank to the carb
