Chainsaw Repair

Removing the piston on these things are is a pain because they are so small .It only has an 8 MM pin with a 9 mm circlip . I use an ice pick to get the clip out .To reinstall I have a homemade driver but even with that it's a chore .Fact I put one in orbit today but as luck would have had several more as spares .

Face the arrow on the piston towards the ex port or to the right while looking at the flwheel .Make sure the gasket is aligned properly .Because of the way the transfers are made it only fits one way . Make sure the ring ends are aligned with the pins in the ring grooves .Slip on the cylinder .Now some people use a ring compsser but I can get them on without .Fact I've never used a compresser on a chainsaw but to each their own .Whatever works .
