Hi, I recently bought an 8N. We did have it running (not that good, and hard to start) when I purchased, but the flywheel was worn in one spot. It has been converter to 12V, and running the flamethrower coil with internal 3 Ohm resistance (no ballast resistor), point set to 0.025" and running AL437 plugs.
We put the ring gear on, and have tractor back together, but something seems strange on timing. It seems we have a good spark (at least on cylinder 1). When trying to find TDC of crank and align with timing numbers, it seems to walk around. Some people say there is two sets of timing numbers on flywheel. I only remember seeing one set on my flywheel, but I could have not been paying attention. Either way, if you turn the flywheel with a pry bar CCW, it doesnt seem to spin the rotor. Is this ok or normal? Its almost like we would get timing close, but then if we moved flywheel manually (not engaging the starter), we would adjust timing..
That being said, there isant really any conceivable play in the distributor shaft (side to side, or up/down). And with the cap off, and kicking the starter, the rotor spins fine. I should mention, all cylinders have 120-125 psi compression. The N I believe is in the 50's... I cannot read the first number, but its X65,xxx. Maybe someone can help me find the year of this tractor while we are at it.
Thanks!!
Andy
