I'm not so sure pulling is a good idea, given the potential for engine damage.
We had an IH 460 way back when, dear ole dad let it sit too long, that and with an exhaust leak under the hood, which must have let moisture in given what I recalled and where it was leaking. They tried to pull it in gear, good thing was it would not budge. This had a rebuilt motor, so the tolerances were not like a worn one.
One of my D7's is stuck, stack was covered, but when I retrieved it from the guy who borrowed it in the late 70's, it had sat a long time when I hauled it out in '03 or so. I was not able to get penetrant in the injectors, but was able to get some through the exhaust ports, don't think it did any good. I machined up a thick rod with a cross piece through it, and fit that to the big nut on the crankshaft on the front of the engine. We tried with a long pipe to turn it over, just tightened the nut slightly is all we did. The heads will have to come off, and I never liked the idea of not doing that, given the damage that can be done to the bore or liners in this case.

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
