Really great engine. Everything looks so well detailed. Thank you for sharing.

I clicked the link from a friends computer and it opened promptly. There is also a download button.

Has anyone downloaded or looked at the Fusion 360 files?

One undocumented change is in the head. I bored shallow pockets to install hardened valve seats (press fit) with a steeper seat angle than shown in the model. Valves were lapped in with 600 grit Clover Compound. Extra tapped holes were added in the base for mounting. Oil ports were added to the...

Here is a downloadable link. https://a360.co/2rA0apm There have been a few undocumented changes along the way. Joints between the gears and cam were never established( It was not working for me nor is it necessary) Not sure how long I will keep this available. If you have interest , get it now.

Thanks for the compliments. I am really glad it has turned out well. I am still working on mounting, fuel tank, usb charger and lights. I started using a vaporizer style fuel tank. It has stabilized the running, but lacks instantaneous demand for changing load conditions. I still may make the...

Here it is in color.

Had some issues getting a video uploaded.

I have had a number of minor setbacks along the way, but I finally got it to run. Between valve seating, carburetor issues, and timing problems it took a while to narrow in to get it going. There is still a lot of details and mounting to take care.
