"commando dogging out at speed???????"


  

          

my 73 commando has a hesitation (stumble) between 70-75mph (about 4200rpm), smooths out til 95-100mph (about 5500rpm) and then just falls flat on its face. i did just file the points and make sure they were set .016, and plugs look great. THIS IS THE BEST IT WANTS TO DO!!!! i m guilty of neglecting it. i haven't run it since last year about this time or earlier. and it would run up til 100-120mph with no problem, no stumble and no hesitation. i always let it run until the gas is run out of the carbs before i put it up. i don't think the carbs r gummed up.
anybody have any suggestions about what may b the problem with it?
thanks, joe
