Nice trick. I only wonder how to manufacture the link between my compressor and the spark plug opening. They're both with special threads..

Thank you John. I have moved my laptop out to my garage, and am now confident that with your guidance, my 76B will run again! Good stuff here.

I have a "leakdown tester" which follows the same principle regarding charging of the cylinder with 125psi and going through the process that John Twist goes through on this video. Thanks John
