Hi, im in the process of rebuilding my carbs on my spx 787.
the Mag carb will not build any pressure when attempting to perform pop off pressure test.
when i pump up the pressure tester the pressure leaks right back out and if i pump fast i can get it up to about 30psi but the pressure doesn't hold.
i noticed my carb base gasket on the fuel pump side leaks while building pressure and i am thinking this is the issue. i attempted to rebuild with a new gasket kit. i replaced the rubber gasket and diaphragm dampner but it still leaks. is it ok to add a small rtv bead on the edges of the carb to help seal?
My pto carb is fine and pop off is at 43psi and the carb hold pressure no problem.
