Leaded fuel

[colbya1]

I have recently purchased a 1969 AC B-12 Garden Tractor. I believe the engine is completely original. I'm wondering if this model requires a lead supliment in the fuel to run properly.

Aaron, I've been playing with these toys for many years. I've never used a supplement, and never had a problem. I've tried different octanes, and 87 seems to run the best. Biggest thing is to keep your carb adjusted properly. A lean carb can cause burned valves and engine overheating. A rich carb will cause carbon deposits, which, if wedged under a valve, will also cause burned valves. If it is running properly you shouldn't have a problem. Rod H.
