Older payware aircraft that had no starter or fuel switch; loaded with engine running, if it died just use CNTRL+E to restart. I added a fuel cock and starter switch but cannot start engine manually, it will spin up to nearly 1000rpm but never start. Hit CNTRL+E, with magento and fuel in any position, and engine will spin up to 600-800rpm, sputter a couple of times, blow a puff of smoke, and be running in five seconds. Can kill the engine with either turning off magneto or shutting off fuel cock, so both are functioning. What have I overlooked.

Starter not working

No battery, so magneto should be providing the spark, whether from CNTRL+E or starter switch. (Though the cfg file shows a 12V 40A electrical circuit, I guess that's default to all aircraft.)
I did try adding a master switch and a panel light, both worked but had no effect on starting (removed both, 90% of the time panels are clearly visible at night without lighting).

Many early aircraft have no electrical system. The Wright Flyer for instance -
[electrical]
max_battery_voltage = 0
generator_alternator_voltage = 0
Magnetos are like a combination generator/distributor, once turning they create their own electricity. Hence their use on many racing cars, where saving weight is also a premium, no need for a battery, generator, and starter. It's only when you start adding lights, radios, electrical gauges, etc. that a full system is necessary.
But in my case the aircraft never had a fuel switch, starter switch, battery switch, etc. but runs fine, and will start from CNTRL+E when needed (engine often dies if throttled back completely, I've tried fixing that also, no luck yet). But it will not start with a starter switch, yet turning off the fuel switch will kill it (so apparently it doesn't need the fuel switch but it works if installed). I still enjoy flying the plane "as-is", but I want to learn why the starter isn't firing it up.

One other thing, the default flight saved in FSX. The default flight needs to be the Cessna 172 and it must be saved with the ignition switch set to "both" magnetos and the fuel selector set to "both" tanks. This does not affect all add-on aircraft, but with some, not having the default flight set to the default setting that came with FSX, the result can be an engine(s) that act as if they are fuel starved or have an ignition failure.
