John - Working backward thru your questions: 1 - That 2-1/2" cap you found on the motor ahead of the distributor is where you add oil to the crankcase. Be sure to replace the cap after filling! 2 - The bellcrank and linkage you found beneath the oil fill controls the radiator shutter - used to regulate engine temperature in cold weather. Chances are the shutters are long gone, but the linkage was left behind. 3 - The 4-postion (L-H-D-B) headlight switch works like this:
L = low battery charging rate
H = high battery charging rate
D = dim headlights
B = bright headlights
Generally leave the switch on "H". Exception: Running the tractor continuously for long periods (hour or more) in hot weather - then move to "L" to keep from overcharging the battery. 4 - Engine smoke could be any number of things. If it's black, the carb is set too rich, the choke is not opening all the way or the air cleaner is plugged. This could account for the slight engine mess too. Blue smoke is oil burning - could be as simple as old, diluted oil (change the oil), or as complicated as worn rings/sleeves (find your wrenches and checkbook...) If the tractor has been sitting a long time, it may smoke some until it has run a while. 5 - Hard cranking. Presuming you have a good, fully charged battery, check for undersized battery cables, loose/corroded clamps, etc. If the starter switch gets hot, it's probably worn out and should be replaced (about $10). 6 - Original battery set up was positive ground. To change your tractor back to positive ground, swap the battery terminals, then use a piece of wire to momentarily connect the BAT and GEN terminals of the cutout - just needs to touch for an instant. (If the ammeter reads backward - deflects LEFT while charging - swap the wires on the back of the ammeter). Get that owner's manual - it's well worth the price! Bob M
