I was experimenting with mine last night and decided to try running with individual spark plugs disconnected. I thought it interesting that on the exhaust side, I was able to run with both cylinders 2 and 3 disconnected at the same time and was unable to detect any difference in performance. Runs smooth at idle and has the same slight mis on accel. Disconnecting 1 or 4 individually made a big difference, even at idle. Plugs looked old, but OK and were not fouled. Guess we'll try new plugs tonight and see what happens.
