I have a Farmall H And a question as well it pertains to timing and indicators that may or might not mean anything. On the crankcase cover there is a indicator pin or that is about 3/4" long and pointed. then on the flywheel ether are two mark one marking is a notch (V) and about a 1/4 turn of the crank the pulley has two notch's. If i align the pointer and the single notch up is this close to TDC or is when the two notch's align straddle the pin, and if one or the other is this a start to getting the timing correct I realize that once TDC I pull the magneto rotate the gears clockwise until the rotor makes two clicks. Any one that can help or clarify would be appreciated
