Do you have any suggestions for the stuck set screw in the pulley?
I just cut one off a Tecumseh 10 hp engine with a cut off wheel on a die grinder after trying everything else from heat to PB Blaster to a three jaw puller that made the pulley unusable anyway.. It was one of the flimsy pressed steel ones though. Split it down the side of the shaft and then used a chisel to open the gap and it slid right off.

Some will use heat, I've used a puller, put pulley under tension and just hit it with a hammer, it will come loose, at first you will think it broke, not for the faint of heart
This is a big heavy duty cast iron pulley on a Sears SS/16 tractor. Would be a big job to saw it off without damage to the crank shaft. I've thought about using heat but I'm afraid that might mess up the crank too. Haven't done anything in a couple of days but plan to get back on it tomorrow. I appreciate all the input and if I have any success I'll let you know.

I've tried to upload a few pictures to show the damage.

I agree, I found a new Honda GX610 18hp for $750 that I believe will work. I know it will be a challenge and require some modifications but that's where I'm thinking now. If there's any interest, I can start a new thread with the repower work progress and/or obstacles encountered.
Threads like you speak of are ALWAYS welcomed! More than likely someone would benefit from your thread. On a Suburban, a repower is lots simpler than many tractors being it is belt drive. Locate the engine where the pulley will be at the same original location, then work around the engine fitting everything else in. This way all belts will be aligned. You can always raise the engine mounts if needed, but I think the GX will be close on crank height.
