I have a 5hp tecumseh bone stock and it ran good for about a year.Than when i ran it full throttle for a mile or two you could fell the governor kicking in big time more and more than usual so i removed the governor the gasket was old and tore so i used hi temp permitex and sealed it good ever sence then it will not run right,lost 50% power and will run shitty for 2 or 3 minutes than dies and wont start for an hour or so.The carb is good and runs good on my other tech.i switched then to makesure it was not the carb.thanks
