Trying to understand what I have. Okay, I have a original distributor and tachometer and a vacuum advance is in place. Which is working the advance?

Brother checked the vacuum. The line is clear and diaphragm holds air but no movement/advancement.

How are you trying to check your advance? The amount of vacuum advance is greatest at engine idle speed Did you watch the timing tape for movement as engine speed changed on the flywheel?

Just checking the vacuum for movement, not timing. The connection isn't moving the plate inside the distributor.

Timing mark on front pulley matches that on the flywheel.

Okay, just got exhaust manifold back. Had to do some grinding so cupped gaskets seat without bending the rims.

Exhaust has been milled before and evidently messed up. Took over 1/8" to get all ports flush to each other. $45 to mill.

Took a temperature drop. Was in the 90 and down to 81 yesterday and 55 degrees this morning.

check the plate is the distributor then ,... cause once the hose is disconnected the plate should retard the timing, just like the old chev
, ford and dodge engines back then. same deal. are u using a timing light?

Well, until we have the exhaust/intake back on and tractor up and running.....
I bought a new timing light. For right now the tractor was running great, started great as long as the throttle was set to give around 1000 rpms. Idle wise it will go below 450 rpm. Tach needle swings from 200 to 400 rpm. Motor doesn't seem to lope, smooth, just the tach needle bouncing a bit.

The old exhaust gaskets were pretty much shot, junk. One had about a 1/4 it gone. 2 others were pure black. 2 seemed sealed good.
Got me was whoever changed the gaskets didn't care. The side walls of the gaskets were all split from the exhaust port ridges.

Again, brother ground around the exhaust ports so the new cupped gaskets fully seat - no rubbing anywhere.

Temperature dropped all day until way in the afternoon. Got down to 48 degrees. Last I checked it was 52 degrees.
