Glad it's running, Dennis.
I don't know if an MQ can do this, but sometimes an engine will stop with its piston exactly at Top- or Bottom-Dead-Center. When that happens, the "Starter" (whether a starter motor or you and me pulling on a cord) gets very little leverage against the piston.
The way the MQ engine flops around when we're holding the STOP button, who knows where it lands?
I started ours today, and as usual, it started the same way Bruce's does. Prime, Try, Prime, Try (maybe one more Prime, Try) and it starts. Ours is from 2002, 420 hours, new carburetor and logic board, original fuel pump.
