gave up and had a new pump built for the 3406 b now i need injectors if i install em my self do i need to reset the jakes or can i just bolt em back down ?

 

It’s best to reset them. Make sure you keep the washers marked A and B where they originally came from.

that said I know lots of people who don’t set the Jakes when they come off, I know lots of Jakes that have a flutter or don’t sound just right too

 

ty ty thats wat i figured if ya take em apart they should be reset and run the top end just wanted to ask
