Mercarb Check Balls

Some Mercarbs use an intake check ball at the bottom of the accelerator pump well with a screen over the check ball.

There are 2 check balls that go in the Mercarb. If one is aluminum then it goes in the pump well (bottom)

The bigger stainless steel check ball would go in the main discharge.

Both check balls for the Mercarb are 5/32″
