The shipper dropped off my new M725 here in Florida from Wisconsin. It looked just like I left it a few weeks ago except it doesn’t start; just sputters and coughs.
The fuel and air situation is good. Before I found only 5 volts were getting to the distributor from a bad primary ground, I opened up the distributor to take a look.
Whatever I did with the distributor made it worse. Now there is no spark, coughing or sputtering.
So, I am going through the process of figuring out what I did when I opened up the distributor. I have on hand a new coil, point set, rotor and condenser. I also have a Pertronix kit I might put in later after I get it running with the conventional ignition. The distributor insides are familiar looking just like the M37. I don’t have all the M715 manuals yet so I’m going to use what I see on this excellent website augmented by insights from the M37 manuals.
I’ll report back once I have it figured out.
