this is the little machine i build just for testing, the windshield motor had a hard time ,i changed a bunch of different pullys and stuff. i decided to put a counter weight on it. wow it loves it. it just works so much better ,i can throw a lot more dirt at it and it doent care, i think it way easier on the motor, anyone with a puffer should at less try this. its on the crankshaft. then i looked at the weather and said what the hell am i working on this.
