I'm beat and haven't felt much like messing with anything in the shop tonight but I did finish cleaning the gasket surfaces and got the gas tank off. Looks like I will be looking for another tank to use.
Just so you know, you can't put a Sears plastic tank on these without modifying the tractor a little.
Step one, remove the entire fender bar/light support.
Step two, turn tank 180 from the way it should go in... (It will pop in between the fenders this way) and figure out where the nipple will be.
Step three, drill new hole in frame and extend the gas line over to the new hole.
Step four, build a new tank hold down strap.
The whole problem is that they used a different seat spring and placed it in a different location due to the hydro filter location, etc. I looked into changing springs, but then the filer had to move, the hoses and holes would've been wrong, etc.
