My first try at a hit-miss motor was not 100% successful. It had to go to the small motor whisperer (ChrisH on this forum). We did indeed get it working and stable. I never felt that O-rings were a proper way of sealing a piston. I bought a piston and rings from China a set off on the next adventure. There were some false steps and there are a few "warts" in the final product. But... its runs and runs well.
My biggest issue was learning how to do ball bearing assembly. There is a very small difference between just right and too tight. It took a little "tuning" to get everything where I liked it. It is wonderful what locktite and emery paper can fix. The final displacement is ~30cc.
If the forum does what I expect the link to a video will be below.
