Just bought this motor and it ran fine but noticed the fuel pump leaks so replaced it, now when go full throttle it bogs down and I have to leave the choke out to get it to do that. It will idle without the choke but sputters. I took the carb off and cleaned but i did not have a rebuild kit. It was filthy. The float is in rough shape. I can spray carb cleaner in it while it's running and it will start to accelerate. I have ordered a rebuild kit with a new float. What are other possibilites. I put the original fuel pump back on to see if the new was bad but same problem.
