Carb problems on rough track

[B1 crew]

Any advise on what to look for, car stumbles in center of corner when track is rough or when jumping small tires inside infield. Runs ok on starts or at higher rpm and on smoother tracks. have checked float levels and normal stuff. E85 650 K.B. Carb 604 crate. thanks for any suggestions. Ed B.

lower the float level

Its probably over flowing causing the stumble on rough tracks Ive had that happen in a mod.

lower the floats a bit as suggested by stock car but going past bottom window is never a good idea

you can try increasing vent tube height or tie the 2 vent tubes together using rubber hose----make sure that you cut the hose at its highest point to still allow the bowls to vent

you can also try an angled carb spacer ----there is a 1 inch version on our website that is legal in most crate sanctions (NOT UMP) ----it was designed for exactly that condition
