I just completed my latest Project...
The engine is Changfa style R175 and is coupled to an ST-2kw head.
This is the first unit I have built which is directly coupled without a belt drive.
To accommodate the power pulses I sized a shaft coupling capable of 30HP even though the engine makes 6hp. ;)
For 60hz power the engine must run at 1800 rpm, however I would like to slow it down to 1500 rpm and generate 50hz power.
This should provide quieter operation, lower fuel consumption and maybe longer engine life.
Apparently the IOTA 55 amp charger that the ST head will be powering accepts 50hz power.
Being that the engine is hopper cooled, it would be very easy to convert to a blanking plate design with coolant connections for circulation through some sort of heat exchanger or wall radiator.
Ideally the system would have auto start/stop based on battery bank voltage (to take advantage of the electric starter). Perhaps something I can work on
Here's a few pics...

Awe - nice job! Love your mounting base. That is one very nice unit! ;D
Nice Job! Looks great.
You're inspiring me! I have an R175a (crank start), and an ST-5 that I've never used. Been thinking of what to do with the engine. Never thought of direct coupling it, but it makes a more compact installation that way. Good job!
