Sound like a good trainer setup.
The TT pro .46 is an outstanding engine... but open it up and inspect for small metal filings. I was given one that had frozen up due to a bit of mold flashing comming free in the intake and "galling" the crank to the case. (3 hours to repair that. I was lucky it could be fixed at all.) Just pull the carb and the backplate.. flush with a little fuel and any loose stuff will come out. (cheaper to waste 2 to 4 oz fuel than ruin the engine) Done prior to running, the gaskets won't be harmed at all.
