Sky-Tec Flyweight high torque, light weight starter, model 149-12LS for Lycoming – $230 unused since overhaul. Bought for O-235 Long-EZ only to discover at installation time that I have 122 tooth ring gear (vs. 149 tooth ring gear). New price for this starter is $355. This is the lightest TSO starter on the market at 7.8 lbs.
