Distributor timing side mount Remove the spark plug from the number one (front) spark plug. Turn the engine over with a finger in the spark plug hole and the ignition switch in the off position until you feel the compression begin to push your finger off the hole. Finish turning the engine over buy hand with the fan or by placing in fourth gear and moving the tractor slowly forward by pushing on the rear wheel until the #1 piston is at top dead center of the compression stroke. Install the distributor into the hole and turn the distributor shaft until the rotor is pointing to the #1 mark on the distributor cap. If the cap has no #1 then just point the rotor to any position on the cap to one of the plug wire holes. Turn the distributor slightly until the points just open and then back a couple degrees in the opposite direction of rotation for the rotor. Direction of rotation for the NAA and up is clockwise. Install the wires into the cap in the direction of rotation of the rotor when the engine is running which is counterclockwise and in the firing order for the engine to the appropriate spark plug in firing order.. 8N firing order is 1243 After the engine is running you can turn the distributor right or left until it sounds best. Not labored or skipping. If it pings when under a load then turn the distributor in the opposite direction of the rotation of the rotor. Or if it seems to try to kick back against the starter do the same. The best place is just adjust to the point that it pings and then back the other way until it doesn’t ping under heavy load. Never mind the timing marks. Zane
