I've had this LB for a year now, 21" with the F engine, new coil, pulled muffler and ports were clean, tune up, clean and lubed everything. Runs pretty good, a bit on the rich side due to carb shaft wear I suspect. Just curious about the internals of the motor. Does this little engine have roller bearings on the crank? Rod journal? Is there a recommended rpm for power and life? Does the cylinder have an iron sleeve? No non-ethanol gas around here, should I use mid grade or better gas? I got a case of lawnboy oil and mix as listed, seems like some extra oil but I'll stick with what they say. Thanks.
