I have a 51 farmall h and am having trouble getting it running and I was wondering if there was any way that they can jump time out of the blue? It ran fine and just quit. I put new points, condenser, plugs, and wires. it ran rough like the choke was on. I rebuilt the carburetor and now it will not fire at all. I set the carb per the owners manual, but when it was running the wires were set on the cap 1 space counter clockwise from where the book said it should be. I put the wires where the book said they should be and still nothing. I am getting fuel and fire but not at the right time. Any suggestions ?
