Color change, would this be a sin?

It is easier to paint things the same color as it is. Changing the color seems to make a bit more work in the details.
Agree though, it is your tractor and you can do what you want with it.

Hi,
If the oil pressure is good, even when the engine is hot and at slow idle speed, I would try the oil additive before rebuilding the engine.
If the oil control rings, or the compression rings are stuck on the pistons, it can make the engine smoke, usually blue smoke is from oil burning.

Combustion isn't perfect in engines, over time it leaves slight goop on the piston rings. That can make the rings stick, so they are not free to expand.
Also if the engine sat with goop on the rings, it can harden and make the rings stuck.

I used Rislone, and have seen it help slow down oil burning in engines.
The Seafoam might be better, I don't know, I haven't used it.
Follow the directions on the can about how much to put in the oil. You might need to drain a little oil out of the engine before putting in the additive, so it isn't overfull.
The Rislone is thin, the last time I bought some, and thins down the oil some.

You could do a compression test to the engine, and see if the compression is good.
Open the throttle fully for the test, so the engine can get air.
