Tomorrow I am going to start pulling the engine on the 1250 to get it rebuilt. I can't find a step by step instructions anywhere (no shop manual for the 1250) so are there any pointers?

The best advice I can give you if this is your first engine disassembly is to take lots of pictures.

from personal standpoint, use an impact on headbolts. and dont snap any, because then you have a fun game ahead of you.

As Brain take pics if it your first.The driveshaft maybe the worst part as they will freeze to the crank often after all these years.Spray some pb blaster on it and let it soak.Also make sure to pull the bolt that is in the driveshaft on the crank or it will never move lol.The driveshaft may not come off the crank and if so remove the fender pan and take it off the pump and deal with the crank end later.Other then that the rest is pretty straight forward.Also remove the battery and gas tank mount just to make it easier.Good luck

If you find a copy of the Large Frame Service manual (IIRC downloadable from Sonny's Bolens website) check Section 7-3. It covers engine removal for the later Large Frames like the 1886 and up, but the operations are the same for the early Large Frames like the 1250 (for which there is no service manual from Bolens).
