Jimmy, if you have the mag set so it sparks [snaps] as the LH impulse on the flywheel lines up with the case mark [at 3 o'clock directly behind & even in height with the center of the crankshaft] & the L/H plug sparks as that L/H impulse mark on the flywheel lines up then your mag is good & you have other problems.. ~On the carb�Set the idle needle about 2 turns out from seated & the load needle about 1 turn out from seated [they should be marked on the carb casting for what they are].. ~If that tractor has been sitting a while the cylinder walls are probably washed clean of oil so start by adding about 2oz of engine oil through both spark plug holes. You could also do a once over cranking compression test but I�m sure you will find low compression. ~Once the oil is added, try cranking the engine over with the compression cocks closed. That will push the oil into the ring grooves & hopefully seal the rings for starting. Those old D�s have a habit of wearing the ring grooves in the pistons & that causes hard hand starting [see post to Michael Esch above]. ~For hand starting that �D� try almost no throttle & full choke until fuel come out the petcocks, then open the choke & throttle a little & try again. ~I have found that in some cases on those �D� tractors [that have sat a while & not been started] won�t hand start with the petcocks open after sitting for long periods. Try cranking it with the petcocks closed [I know it isn�t easy but you DON�T have to turn it fast, just slowly turn it over].. If you can�t crank it with the petcocks closed then only open them slightly & try it. ~If it just won�t start by hand you might have to pull start it the first few times it runs.. Once it is running a few times it will then probably hand start good. ~If you haven�t already done so install NEW spark plugs & gap them at .035� instead of the recommended .030�.. ~I guess here�s the bottom line�IF, you have a spark at the correct time & you have fuel coming out of the petcocks while cranking then it should start.. If it still won�t hand start you probably have ring sealing problems so try the oil in the cylinders & or pull starting it. Any questions just post back or E-Mail.. [email protected]
