Already changed the diaphragm. I get half throttle and it wants to die. i noticed the tank was leaking a bit. could this be the problem?
 
replace coil and plug to be sure its not a fire problem. If that's good try a different tank. I have seen them get a hole in the cup that feeds the jet. They won't hold enough fuel for a pull under load. the engine has to have more fuel when it's under a load than when it's on the stand.
 
I put new gaskets on it, and a new tank. Last night was the same thing. coil and plug are next. thanks for the advice. after that, if it doesnt work im clueless.
 
I coil and plug don't fix it it's probally a valve seat starting to come loose. It rare but I does happen and only when the motor gets good and hot.
