Hey,
I have never opened one of these little buggers before and I want to open mine to check that it still looks ok and also to give it a proper cleaning. Im most interested in removing the piston and the sleeve. How would I do this and do I need to do anything particular when opening the engine? Also whats the best way of getting rid of inner engine gunge ( my piston is black! )...thanks for any input!
