Hey need to pick a expert on this little motor, runs like new, starts on the first pull, revs up fine on a hose, but when you put in under load it bogs down and does not go full throttle, I have soaked the carb twice, new reeds cage, fuel pump gaskets, plugs , set timing at 30 degrees, tried a separate fuel source, checked spark under load, both cylinders firing good, man this little engine is kicking my ass.
