I dunno, you mention a tight spot, and choppy cranking electrically. There may be a problem internally, or with the gearcase like others have been mentioned. You may want to soak the cylinders with cleaner, perhaps pull the heads if it cranks the same with the gearcase off.
Does the engine have a bubble back exhaust cover, if so it is a 135. 115s had the flat back exhaust cover. The 135s definitely had more compression, and everything needs to be right or it might crank slowly. Regular jumper cables may not big heavy enough to crank this engine effectively. How does it crank with its original wiring being used? The battery needs to be relatively heavy duty and fully charged as well.
Again, I wouldn’t attempt to start the engine if it continues to have a bind or be choppy while cranking.
