I have a 41 H THAT I've recently finished restoring.The tractor has been converted to 12V,THE ORIGINAL MAG IS GONE,AND IT HAS A M&W LIVE HYDRAULIC PUMP ON IT AND AN IH DISTRIBUTOR ON IT.The tractor sees no work,and is a hobby tractor,and is kept inside out of the weather.The problem I'm having is occasional hard starting,rough running,and bad condensation build-up inside the dist,to the point that I can blow the water out with compressed air.I have a 12v coil on it now,and I added a ballast resistor to the circuit between the ignition switch and the coil.The condensation fouls the points.Sometimes it will only run on 2 cylinders,then smooth up and run fine.The coil is old,but it doesn't appear to be getting hot.A look inside the dist now and you'll find a rusty film build-up on everything.I tried leaving the dust plate out of it,that doesnt appear to help. The points don't appear burned,but the water inside rusts them I'm on the verge of changing it to electronic ignition. Any one encounter similar problems-I did a C last year and had no ignition problems,and they shared basically the same ignition parts.
