If your beaking up on top,your too rich on your main.It sounds like your trying to change all the jets at one time.I would just do one at a time.Once you get the main,mess with the pilot,then mess with the needle,or however you want.But i would do the main first,least then its a little more ridable that way.I'm in Pa too,how close are you to Uniontown or maybe even Farmington.What type of carbs you have,stock??
