I want to overhaul the 4HP Briggs engine on my Arco bike (next in line for restore). Problem is, I can tell if carbs and gasket sets are for the newer 4HP or the old style 4HP engines. I have the old style. Mine has the pull tab choke to kill the engine. Is there any service manuals or parts lists to aid me? I used Gunk foam on it yesterday and it cleaned up nicely. There was an 1/8 inch crud all over the engine. If pic of engine helps, I will be happy to post one. Also, using the Gunk, I saw the origional color of the Arco frame, it was a real light blue (retro light blue).
