Just got an 1872 Hydro and starts great when its cold and never shuts off when its hot but when I shut it off I can start it right back up right away but if it sits like 10 mins, I dont get a spark, the engine turns but never fires. Checked ignition and noticed that the yellow wire when cold gets a charge but when having the starting problem gets NO charge. Yellow wire connects to white that goes down into the engine with the spark plug wires, Coil wire?? Is the coil sending charge back through the wire to the ignition?? Is my coil over heating when I let it set too long and it needs to cool off? I am assuming that the fan on my drive shaft pulls/pushes air through the engine. I have spent HOURS trying to figure out WHY. Please help.

I don't know the tractor. You might say if it has a coil/breaker or a magneto ignition if 'charge' means voltage measured with a VOM and also how many hours it has. If it's a coil/breaker ignition and it has a fair number of hours, a heat sensitive coil isn't a bad guess. Sometimes heat-shields go missing too. ....
