I have a 440, it was not getting gas. I took apart fuel pump cleaned & reassembled. Now I see it is getting fuel. It will only start if I put my hand over the carb. And will die if i do not "feather" my hand over the carb.
That is it. My motor is a 550 not a 440. Does anyone know where i should start my settings at with aftermarket pipe & intake? Also I read a little about needing a fuel restrictor since my rev limiter has been removed. Do i need to add this? I have a drilled out aluminum bar ready to install if needed.
