This is a vacuum petcock... it does more than allow fuel to flow...
It sucks... literally... it uses engine vacuum to open the flow...
When this goes bad,.. it sucks air and leaks fuel...
This causes all sorts of problems...

That is why, it's our first check in any fuel/running problem...
It must be ruled out 100%, before testing anything else....

A stock Savage should easily go well past 80,.. and be pushing 90mph before petering out...
...45,... is a moped...

When the diaphragm in the stock petcock fails, it can allow fuel and air to enter the engine through the vacuum line that attaches to the inlet tract on the right side of the carb.....which will negatively affect how the engine runs. It is also possible that the failed diaphragm can prevent proper fuel flow to the carb through the fuel line that attaches to the left side of the carb.....which will negatively affect how the engine runs. By disconnecting and plugging the vacuum line, and turning the petcock to "PRIME" - you are bypassing the vacuum operated feature of the petcock. If the petcock circuit is not plugged with crud from the fuel tank, this test should allow you to have a normal fuel flow.

The test is not a permanent fix however.....as you will not have any reserve feature and can run out of gas.
