Hi Beuh . I have built an engine using this cycle of operations . It is a 2 stroke engine and it completes all 4 cycles in one revolution of the crankshaft . There are two valves .The inlet is atmospherically operated and the exhaust which is located about half way down the stroke is spring...

Why not put a light shim under the o ring to tighten it up , save you making a new piston. Vince

This is a link to my version of a simple I.C engine based around Henry Fords engine. In my opinion they don't get much simpler than this https://youtu.be/ICOC9Kvq488

John I would also like to wish you all the best and say thanks for your contributions from which I always learned something. Vince

His workshop and bike are a credit to him ,I could do with taking a few leafs out of his book. Vince

Looks good and runs good, can't ask for more than that Vince

You could fit a Lucas spring starter ,just wind her up and away you go. Vince

That book will make interesting reading . Thanks for uploading Vince

Could you turn the flywheel in the milling spindle and hold a cutter in the vice. Vince

Thanks Dave

Thanks Pete Their was a bit of head scratching along the way but I got there in the end.

Thanks lads. It was a bit of a scrapheap challenge.

This is an engine from bits and pieces I had lying around ,the frame is of welded construction ,cylinder is from old hydraulic ram , flywheel is old hand wheel ,piston and head is cast iron ,piston rings from old shock absorber. This is a link to it running. http://youtu.be/F2AWQqTTsFI...

Sorry I just presumed your spindle ran on taper bearings (should have read the whole thread) Vince

Car and trucks use taper roller bearings in the wheel hubs and have about 3 thou floating clearance when assembled and they put up with severe punishment from the road surface without any diverse affects so I don't think a whack of a hammer to release the morse taper in the spindle would harm...
