Hi anybody....does anyone have a pic of where and how all the linkage goes to the carb
mostly the choke linkage goes ?there is a loop of wire on one end of the choke linkage .

can anyone recommend a good brand of synthetic oil?

trouble with one exhaust valve seat insert coming loose cause it to start burning oil until after it was fixed? (Maybe)

hope some one can answer these questions .....thank you!
