once it goes wheeee ,,, well it then slow down and run at say 2 rpm ( very slow ) ? because of it age, I'm guessing it has a wiper type pedal, take it apart and see if the wiper touch's every contact point..
you COULD alway use a multi meter and check the voltage out of the pedal, Thats easier said than done...
I find some of this is from a belt being to tight, I say that because of the buzzing sound. meaning the motor is getting power, but can not move
