OOOOOOHHHHHHH!!!! I get it now! You’re only supposed to bump compression to the left, but the engine will fire while the piston is past TDC and start running CLOCKWISE.
“It is never necessary to crank motor over compression”
Makes sense now. THANKS A LOT!! That was very helpful!!!

You’re close. You want the plugs to fire exactly when you let go of the knob. You let go of the knob where you get the best bounce. When the motor starts it will be running with the spark happening at past TDC. But the spark happens before TDC on your starting swing, the plugs fire, the flywheel change the direction your spinning it, and the motor keeps running forward. Try this. Turn the flywheel clockwise till it stops as compression begins. Now slowly bring it back counterclockwise, listen for a snap. That’s is the points making contact to fire the plugs. You want that “snap” to happen just when you’re letting go of the knob. If you go back to the video of me starting mine, I may have had the timer too far to the left, and the points weren’t “snapping” and I wasn’t getting spark. When I moved the timer slightly to the right it took right off.
There is no air control on the early motors. If they had carburetor it would be wide open all the time. The speed is controlled solely by the timing. Slow – the points fire past TDC. As you advance the timing to TDC, and beyond, the motor runs faster. Once you go past the point where its increasing in speed, bring the timer back a tad. That’s full speed. Any more and your over advanced.
Edit – I was think other Super Eltos. Because of the gas tank you cant over advance a Ruddertwin.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
