Was a blog on here the other day about this subject. I happen to be in my Ford manual today and it said just a sort of thing. "At 50 hours, retorque the head and readjust the lifters with the engine warm after an overhaul." It also said to put the head gasket on dry with no sealer or other preparation.
I took exception to this. I use Kopper (head gasket) Koat, do not retorque and do not readjust.
I have a new tractor with 100 hrs I just put on it. No where in the data, nor no conversations with the selling dealer told me that the engine has to be "tweaked" after a little break-in (50 hrs).
Not only that, I never had a new car/truck back to the dealer at 50 hrs for a head torque tweak (lifters were hydraulic so they would obviously be exempt).
So why, in all their mighty technical insight, would service manuals of yesteryear suggest what I said? Doesn"t make sense to me and I"m not about to do it.

To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
