DT50 - why cant i go up hills (even very small ones)

As far as the inlet gasket goes its a lot easier to replace than the base gasket so you can save using gen gaskets, just use an old cereal box and cut out a new gasket using a very sharp knife. Using a smear of grease all over the gasket will help prevent it sticking and promote a good seal.

Another tip, to make life easy, pop the gugeon pin in the fridge the night before you fit it as they can be a bit stiff, cooling it will make it shrink a tiny bit and it will slide in real easy.

Also, put one of the circlips in the piston on the bench before you start. The rags all very well but this way you reduce the chance of dropping a circlip by half.
