I have used a product called Sea Foam. Seems to work great, and got it at NAPA. Used it on my old International Scouts with good results.
Just follow the directions on the bottle. Run engine until warm. Pour down the throat of the carb unitl motor stalls. Wait 15 minutes, and fire her up. Smokes like hell, so make sure the wind is blowing in the neighbors direction.LOL.
Do a search at
www.binderbulletin.org in the tech talk archives and you will probably find alot of info on it.
Thanks
