I'd assume this thread will likely be familiar to anyone whose ever dug into a unit that's been sitting for at least a decade. FYI
Day 3 of being a Cub owner.
Put 4 tires on the donor(possibly) 104 unit so I could move it around some after washing it.
Got it set up on the hoist and dug in a little last night.
-Removed the fuel tank
-Removed the carb
-Removed the S/G
Whatever gasoline that was in the system is basically caramel. Brown and nearly solid. My intention is to rebuild as many of the original parts I can without compromising reliability. Both butterflies in the carb are seized tight, and it took a lot of work to even get the needle valve out. Carb is soaking until I get home from work.
The intake port had some rusty "fuel" buildup in it that I was able to scrape and blow out with the air gun and some penetrant. Forgot to snap a pic before-hand.
The intake valve appears to open and close fine, but it's rusty enough that I'm contemplating pulling the head and cleaning the assembly for peace of mind/inspection opportunity.
Fuel tank appears solid as far as I can tell. Going to try to remove the prehistoric muck with the steam washer later today.
After it was dug out of the woods, I found the S/G stuck until I put some force on it by hand. With that in mind I just took the thing off and tore it down once I got the tractor into the shop. The bearing on the pulley end is pretty horrible.
Checking out the points when I get home.
Rebuild kits for the S/G and Carb are on the list for now.
