This is my problem when i try to go full throttle my engine starts to miss like it is starving for fuel. it will idle all day when i hand line i can run 3/4 speed no problem it is just when i try to open it up all the way is when the problem occurs. also if i crank the handle to full throttle out of the hole it will miss unless i back it down and it takes me longer to get on plane any suggestions anyone is the fuel pump going bad?
