Only while running at 2k-3k rpm the carb spits gas from overflow tube.
ive rebuilt the original carb with all new seals n orings then later purchased new carb and have set and adjusted float on both carbs multiple times with same result.
ive noticed the engine mounts are rubber and cause large amounts of vibration at that rpm so I’ve made a steel mount to decrease the engine shake.
now there’s no more engine shake but still dribbling out of the hose.
mid it possible the 3hose fuel pump is creating pressure in the carb?

 

check to make sure the carb/ fuel tank vents are not blocked or pinched.
