Well, the PowerStart arrived.

The part that attaches to the engine flywheel doesn't fit pocket bike engines. Its bolt holes are 32mm apart, while the flywheel holes are spaced 40mm (The PullStart was made for smaller Chun Yang(CY) engines).
I tried to fit the PullStart onto my spare Tanaka 47R engine. The plastic cover is a shell for the pull start of smaller CY engines. It'll bolt onto the Tanaka if I drill out the cover's 4 mounting screws.
To use the PullStart on the Tanaka engine, I have two options. One is to weld a 14mm socket onto the TroyBuilt Bit-Starter:

Then a cordless drill would spin the flywheel's nut. The guide bushing is smaller in diameter than the 14mm socket. It'd have to be unglued and a larger one installed.
Another alternative is to drill and bolt the Power Start directly onto the Tanaka's starter pawl:

This might not be a good option. The pawl is very thin cast aluminum. In time, it looks like it'd fracture and fail.
Two bolts with flat heads would be needed to clear the engine block's reinforcing bosses.
