Thanks for that. Just what i needed There are no rings on the piston itself so I assume the taper in the sleeve is to help with compression when the engine is running. I have freed up the piston and it will turn until almost at the top. Should be interesting when I fire it up for the first time Current Build:-

The starting of a new nitro engine needs a little patience, but after a few start-ups/runs the internal components will have bedded in, but take great note of the running-in procedure and engine care if you want engine longevity.

Not withstanding my minor issues with the construction of the engine.I have completed the construction so far and am now waiting for the next set of issues to complete. Only another 4 weeks to wait GilShapley attached the following image(s): Current Build:-

For the first 2/3 tanks of fuel, be gentle on the throttle and run the model in a figure of 8 pattern, but do not apply full throttle during this period, and let the engine cool between runs.
