    Diaphragm Help

    Hi,
    I'm Working on my GP760 I took carbs off to try to fix low end bog 2000- 4000 Rpm was dead by changing "Pop Off springs" to lower pressure. When I took one cover off Diaphragm looked like it was installed with small metal pin to outside of carb . Other one looked like in was facing float assy. What way are these to be installed? putting on K&N flame aresstor at this time also
    Thanks,
    Jesse

    If your carbs are 38-44mm the part # is BN44/145 on the rebuild sheet.

    And the pin goes in to the fuel bowl.

    Your carbs are the same as a blaster/blaster2 and some superjets.
