Always have your spark adjustments on mag set in the cranking position. After engine is started these adjustments can be moved to the run position. Always start up and shut down the tractor on gas even if it burns distillate or kerosene. These heavier fuels will only burn when tractor is warmed up. Most old tractors had cranks but a few (like John Deer) had fly wheels that you turned for starting. While cranking, always lift up with right hand with thumb on same side of crank handle as fingers. This apply's to most international tractor's as well as others that will fire near the top of the upward motion of the cranke or just a little past. By cranking with right arm this will allow you to pull crank a little over and past the top center of crank motion. Using left arm will give you a messed up grip and a tuff time of cranking past the top center point of motion where the spark ussually is. If you have a magneto on the tractor you will sure learn what the clicking noise is. This noise of the mag is normal becuase this is what retards the spark a little while starting. When tractor is started and reaches a certain r.p.m. the noise will stop and the spark will be advanced. This is normal. An additional adjustment can be made on mag for further advancement or to retard. This is done with a lever on the old F-20. Not sure about other models. Some makes and models may have a different firing position in crank motion. Your stants and motion will have to be created according to where that firing is in the motion. Here are a few tips and rules to live by. Never crank in a downward or continueus motion. Always stand clear of a possible kick back and use the correct grip on the crank. Always make sure the tractor is in nuetral before starting. Get a chocking and throttle setting pattern that works good and allows quick starting. Never try to immediately engage the crank when the engine stops turning while it is dieing. (I did this one time and the engine run backwards a little bit after I engaged crank and both arms got wrapped up and my feet went into the air and I landed flat on my back.) Beware of crank flying off the tractor during a kick back. I have seen crank's travel a pretty good distance if they happened to be thrown off during a kick back. Here is a tip on cranking a tractor that is also battery start and also crankable and has a distributor. There is no do it yourself spark adjustment on a distributor and so you just have to crank. There is no clicking noise but if you listen really close you can here the spark jump the points. These will kickback alot more than a mag seems to. When your tractor doesn't fire at the end of your crank motion sometimes there is a little bounce to the engine back and forth. Just remember when the points close and open again you will have a second spark on the same cylinder which is differnt than the mag which won't fire again untill another crank after delivering the initial spark. I believe on fly wheel tractor's you grip and pull your hands upward and over the top of flywheel. You may (like I said) have to change your stants or motion a little if the spark isn't near the top of crank motion. Just remember to put removable crank in secure place after starting. Good luck to you and it is a good feeling to crank start something and run it all day just off of your initial pull of the crank.
