Dolmar saw part 2: Crankshaft bearings and seals 

In this part I will replace the crankshaft bearings and seals of this 2-stroke engine. I bought 3 Dolmar power cutter saws (2x PC-6112 and a PC-6114). Can I fix them and sell them, making a little profit? The Makita EK6100 and EK6101 are the same saws as these ones, only with an other color.
