fouled plug?

Turns out it was fuzzy corrosion growing on the distributor cap terminals. Put on new plugs, wires, cap and rotor. Pulls like a locomotive.

Tomorrow I'll be sorting out lights, stupid neutral safety switch, and hammer out a plate to go under the shuft boot.

It starts with the key now, both reverse lights work, and runs pretty good.
Only thing left is to run new exhaust, do away with the vacuum switch garbage, and finish the front drive shaft.

Something didn't seem right with the speedometer so I checked it with my GPS. Only about 15 mph fast.

rong speedO gear or tooooo smaller of a tire

Gotta be the gear. I have 235/75/15 grips on it now. Funny thing is that it has the original transfer case and cable.

gota add more teeth

At risk of sounding stupid, how do I go about doing that?

Never mind. Found it here.

theres about 5mph difference pre tooth change. yours is 15 mph fast, add 3 teeth

Many thanks for all the help.

My truck was originally an automatic. I'm still using the original transfer case mounted to the FM145. Do I need to pick a gear from the automatic set or manual set?

find out how many teeth are on the gear you have now

Didn't get to the speedometer today but I did get rid of my vacuum leak as well as all the emissions junk on the right inner fender. Found a rat's nest in the blower and my fan motor is bad. Truck idles smooth and pulls strong.
Got it stuck in the back of my yard trying to turn around and remembered I don't have the front drive shaft in yet. Had to fire up the Willys and pull it out. Won't do that again.
