Solenoid diesel injection pumps

Darn, I carefully drilled a tiny hole for the spill port, and as I was afraid of, it now spills everywhere, all the time. I'll probably have to make one or 2 replacement pieces to fix whatever I messed up. Not sure what that is yet.

Can you thread the hole and block it with a screw, to give yourself the chance of redrilling the spill in a different way - before you remake all the affected parts?

Or use the erroneous spill hole to run a mini accumulator?

"As for my dream of 5 cylinders, that would mean that there would always be a cylinder in each stage of the engine cycle and if there is enough mass in the webs, the flywheel would not need to be very big."

Wouldn't the same be true for a 3 cylinder engine?
A 5 cylinder is cooler sure but a three would also always be in a power stroke I guess.

Anyway if you can make your 1 cylinder working well you could make another with how many cylinders as you wish for!
