It's not hard at all. Remove the coil wire from the top of the coil, slide the bail off & then remove the distributor cap. Remove the two bolts holding the distributor to the block & put the distributor on your workbench. Set the points at .015 on all 4 lobes of the cam. Check for continuity w/ a meter before you put it back on the tractor because it is easy to ground the condenser wire to the housing. while others may disagree, don't worry about timing. The distributor has an offset tang on it's base & is almost impossible to re-instsall incorrectly unless you force it. Regarding EI, the 9N has a front mounted distributor. Unless the tractor is already converted to 12v, an electronic ignition (EI) for the 6v frontmount is not a wise choice. The 6v coil is really designed to run off of 3v (that's why the ballast resistor is in the circuit) Because of the precise voltage requirements of the EI, even a slightly discharged battery will result in a 'no start' situation. While a 12v conversion & EI will give many years of effortless operation....it does not come w/o problems. The first is cost; compare the costs of annually changing the points/plugs/ condenser/ rotor ($20) vs the cost of a 12v conversion ($145, plus $40 for a 12v battery, or $185) and add to that the cost of the EI ($150) and you get a 12 year pay-back. The second problem is that an EI is quite unforgiving of polarity reversal & other common mistakes of tractor ownership; hook up the battery cables backward & you fry the $150 EI. Of course, a 12v conversion & EI installation can be done by a skilled mechanic for less than $235....but, the same skilled mechanic could fix the problems that are being "solved" by the 12v conversion & EI installation in the first place. Simply put, these are low HP, low compression engines that start & run just fine off of 6v & points. Unless the owner needs to run 12v auxilary equipment, or has a worn out engine in need of a rebuild & wants to buy some time by having the faster spinning 12v to improve starting.....a 12v conversion is not really necessary. Likewise, an EI on an N is a lot of overkill.....IMHO!
