Default Re: "Doodlebug"

Before running.
Exhaust header looks like it has gotten very hot, looks like the spark advance lever/rods are missing. If the distributor upper plate is set for retarded that could be the cause. Might be best to add back a spark advance control. If it is set advanced that can be hard on the motor bottom end as there is a tendency it will attempt back kicking during starting. This is also very dangerous if starting using the hand crank. Maybe rig up a push/pull cable if the lever/linkage in the steering column is missing?

Am not familiar with the trans items, other will have to comment on lubrication for those.

Also get rid of the rubber gas hose from the firewall to the filter and carb. Dangerous if it leaks with exhaust header so close.

Toss the 4 blade fan, they are well known to stress crack and throw blades. Damage to the radiator, water pump, hood is likely. Could hurt or kill someone. Not good especially with plans to run in parades. Replace with a 2 blade aluminum fan, would look out of place but you could treat it for false aging. This is a #1 safety issue.

Drop the oil pan and clean out sludge if present. With the pan dropped clean the oil pump and oil pump screen. Take the valve cover off and clean out the oil galley, and clean out the 3 oil passages in the bottom of the galley that feed the Babbitt bearings.
Change the motor oil. Keep an eye on oil condition, once turns blackish and change again, it may get dirty 1st time quickly if there was sludge during teh above clean out.

If gas is old drain clean out tank, fuel lines, and carb bowl before turning the motor over.

When rewiring - add a fuse. A very common basic fuse kit is supplied can be purchased from Model A vendors, and the kit mounts to the starter.

Oil the distributor and generator. Additionally lube the distributor cam.

Once running

Drain and change all fluids, grease all grease zerks, special care to only give a partial pump of grease to the zerk closest to the block on the water pump.

Back flush, then flush the cooling system, 1st time add water/detergent (such as Dawn) and run the motor for awhile, them back flush/flush out oil/grease, then additionally with just water. Then drain and use distilled water/rust inhibitor. Additional treatments more aggressive may be required if it overheats.
