G`Day Raymason. I have fixed a couple of these Brush SCAF type generator heads. They are unusual in that the rotating armature incorporates the generator windings with slip rings and also a starter motor/dc generator with a commutator ring. Your model appears to have 8 slip ring brushes, so you should be looking at 4 slip rings. My best guess is that you have one neutral, one 240 volt and two 110 volt slip rings.
There are four commutator brushes which feed the built in 12 volt DC starter motor. This also acts as a DC generator which recharges your battery while the generator is running.
The engine RPM determines the AC frequency, yours appears to be set at 1800 RPM to give you 60Hz to match the 110 volt/60 HZ grid in the USA. You may need to reduce the RPM to 1500 if you live in an area with a 240 volt/50Hz supply.
The `A` at the end of the engine serial number normally indicates that this engine is designed to turn anticlockwise.
Could you please post some photos of what you find as you investigate further.

Good Day Rene, Yes the manual specifies .05 mm (0.002 inch) for both inlet and exhaust, to be set with the engine cold.
Stationary Engine Parts in the UK should have all the gaskets you need (www.stationaryengineparts.com), failing that you could try Mead Plant, also in the UK. Rob at Old Timer Engines in Australia has the gaskets but postage might be expensive and slow.

Well done VP, a beautiful restoration and the non original fuel tank looks like it grew there. I particularly like the homemade trolley. Looking forward to seeing what you decide to restore next.

Hi Beaka, I owned and ran an ST2 Startomatic for many years. I am guessing that your fuel shut off solenoid is the same as on my SOM. The governor, governor spring, injector pump rack and linkages are all internal and get lubricated with sump oil so they wear very slowly.
The fuel control solenoid and it`s linkages are all external so they wear much faster because very few people bother to lubricate them. These can easily be adjusted to shorten or lengthen the linkage as required. Another issue with these old solenoids is that they get filled with dust,rust and other detritus that prevents them from achieving their full travel. Adjusting the external linkages is nothing to be afraid of. A couple of pics attached.

Hi Listerational. How much load do you have on your 10/1? The more the load the more the fuel injected and the more heat that will need to be dissipated. A modern car radiator ought to be adequate if you consider that most small 4 cylinder engines only produce about 100 HP. So, in theory you have 10 times the cooling that is required, however your engine is stationary rather than going along the highway at 100 KM per hour, so it lacks the airflow normal in an automobile. Modern vehicles generally have a temperature sensor mounted in the top of the radiator, this is connected  to an electric fan so that your engine does not overheat while you are sat at the traffic lights. You might want to consider implementing a similar system.
At sea level water boils at 215 fahrenheit. Your engine is running at slightly higher than that so it ought to be boiling however a pressurised system will boil at a higher temperature. Lister/Listeroid engines were never designed for a pressurised cooling system, the cylinder head gasket isn`t upto the job.
You don`t say how your radiator is mounted. Most people assume that it should be mounted verticals as it is in your car. This is incorrect for a stationary engine, it is much better mounted at a 45 degree angle in a thermosyphon set up. This allows the thermosyphon to work while also allowing natural airflow through the radiator. In your case you have a water pump in the system so you should probably mount the radiator near to horizontal to achieve the maximum natural convection cooling through the unit.
I  am concerned that you have an electric water pump in your system. Does this have a bypass? Without a bypass your engine will quickly overheat in the event of a pump failure.

Well done VP. Your new pipes look excellent. Glad you are feeling well enough to get back to what you love doing.

Hi Veggie, I am a little curious as to what you are trying to achieve. You have told us that you have a 1000 watt grid tied inverter connected to a 24 volt DC battery bank. How are the batteries being charged, solar panels? Are the batteries being charged from the grid during the day and discharged back into the grid at night?  Are you trying to run off grid at night? Much more info required please.
