It will only run at half throttle
I bought a new carb and tune-up kit and replaced the old ones. I pulled the gas tank to check for any leaks. I replaced the gas cap. It starts right up and revs up to speed only to half throttle, anything past half throttle it bogs down dies. After I let it run for a bit and shut it down the hose that has the breather end leaks gas all over the place. Any ideas.
