has power but breaking up when giving it the gas help do you think it might be the valves and how do you adjust them as i want to learn and not spend much money

 

Bob; it sounds like gas flow so I first have to ask you some embarising questions. (sorry) ,have you tryed new plug ,clean air filter , or try running some quality carb/injector cleaner ,I would check all these first because the praire modle is usally quite reliable,you may just have to much oil in your air filter I'm sure it's somthing simple like that. I hope I helped you in some way brother.
