..to have after u fuel up ur tank the fuel to start moving along the line to the carb? is it bad or its ok? i got a hemo to pinch off the line till im ready to start it..

it shouldn't matter. usually it is an a*s to get guel to the engine.

If the tank sits as high or higher than the carb, it's gravity at work. The same problem I'm having with one of my boats at the moment.

Is it bad to have fuel flowing to the carb before you even start priming?

i was havin the same prob with the stock tank i didnt even need to prime it it alredy went to the carb as i was fillin it thats y it was flooding cuz it filled up the engine so i hope the hemo trick works..

It appears to me that you are filling the tank through the pressure/vent line with the supply to the carb still connected. If that's the case, then you are building pressure in the tank due to the fuel coming in and pushing it into the carb. Try filling the tank from the supply line to the carb and let the pressure/vent line be the over flow.
