Which direction should l point the marker on the cylinder on my 15.tamiya engine? and where should the opening in the piston (little hole) point?

l'm so stupid, l took the parts apart and don't know how to assamble lt.

Help please!!!

The little hole in the piston should face the front of the engine.

As for the orientation of the sleeve, is there an alignment pin on the case? If so, that's where the slot on the sleeve goes. If not, you're going to have to line up the exhaust port in the sleeve with the one in the case. The exhaust port is the largest port on the sleeve.

I hope this helped.
