I have a 1982 Toro S200. I just rebuilt the carb and it is starting up the best it ever has since I have owned it (about 10 years). My question is, what is the correct RPM range? On my 2 cycle mowers it's between 3100-3300, but on this blower it seems too low and it smokes a lot at that setting. I've set it by ear and have gotten no smoke and better running, but I'm at about a range of 3600-3800. Anyone know the specifics for these old Tecumseh 2 strokes? Thanks in advance!
