Title: gx390 fuel system
Post by: Chris Matuschka on July 09, 2013, 06:30:53 pm

Guys, I have a gravity fed fuel system on my gx motor. Running a stock style carb will I need to add a fuel pump or will it flow enough fuel? And if I need a pump will the needle valve need any mods to keep from overflowing? I am going to start running it with just a billet wheel and valve upgrades until I save up for a can and rod so I can get a feel for the chassis.
Thanks

if you find you need a pump the carb will handle it with no mods.

Thanks George, trying to keep things simple but reliable.
