Ya, I saw that connecting rod.
So I took the circle clip off the end of the rod and was able to tweek the rod and now all 4 plungers work together corectly.
The tricky part was to get the tiny circle clip off without it flying off and loosing it. So I put a shop towel under the carb and the engine. I took one of those electricial trouble shooting light. At one end is a clip and the other end is sharp and pointed. I took the sharp end and poked it in the slot away from the open clip end and applied some pressure. The clip came off gently.
Now to get the clip back in without loosing it. I was lucky with a needle nose and it snapped in with out flying off.
