Second question. When I hooked everything up, everything seemed to match very well. All the holes lined up, connections were easy, until the very last connection. The old engine connected to a 4-pin power regulator/rectifier. The new connection that came with the engine is a 5-pin. When I went to start the machine, I hear clicking, I thought I heard the starter turn one revolution, but then just clicking as though the battery were dead. I hooked up a portable jump-starter and it did the same thing, only the clicking was faster. Pushed the brake, same thing. My guess is that it's partially how I had the tubeing hooked up and partially related to the regulator/rectifier (I had plugged back in the old, 4-pin regulator). How critical is it that i get the 5-pin regulator hooked up? Also, I noticed that the enrichment auto-choke began to get warm/hot when I forgot and left the key in the "on" position. I'm hoping I didn't damage anything. Andy advice on that? Or how to get the engine started for the first time? Here are some pics of the regulators:
