Friends, Thank you for you patience in waiting for me look into this again! I followed the six steps that Rivets suggested with the exception of cleaning the selenoid connection down to bear metal. Today I was able to get the engine to fire for two reasons. My son, after reviewing the schematic (see attached), noticed that the small red wire coming off the positive side of the battery needed to be connected to a black wire (see attached picture entitled "Black to Red" of a black and red wire connected with a red wire nut). In picture you should see that black wire going about 3 inches to a Y to two red wires. One of those red wires goes to my 15 amp fuze and then back out again. the other wire goes to a harness with multiple wires. Once he connected, I was able to get the tractor to fire, but, only time enough to burn the starter fluid I sprayed directly into the carborator (the 36 second video I made to capture the firing was too large of a file to register on this site ). I repeated this drill numerous times with no success getting it to fire up and run. After the starting fuel fires and stalls, I have had it cranking for up to 30 seconds without firing. thoughts?
