Daniel, your write-up was superb and covered most of the idiosyncrasies of these wonderful engines. One additional point made by Bruce and I definitely concur...the needle valve on the carburetor top is very sensitive and has a major impact on how the engine runs. I have mine "set" at approx. 1/2 turn from closed position, but I mess with it regularly seeking the perfect wave so to speak. I have clocked mine at roughly 55 hits per minute when dialed in well.
I have experimented a bit with Zippo...first using 5 parts Zippo to 1 part Marvel Mystery Oil...TOO much pink oily residue resulted. Currently using 10 parts Zippo to 1 part MMO, but enough pink residue collects that next batch of fuel I make up will be 15 parts Zippo to 1 part MMO. I want to keep backing down the oil content to avoid fouling the spark plug and have a spare spark plug on order should mine fail me. I like to make "batches" of 50 ml mix as I have a nice screw lid container with graduations on the side (similarity to a urine sample bottle is purely coincidental)
Like you, I would like to add an LED like one of our members showed. I have looked on eBay and Amazon for a source in the range of 4-5 volts...but lowest I have found is 12 volt. Any suggestions from anyone on a source would be appreciated. I personally need the LED to warn me to shut off the switch when I am done. I have now left it on twice and wasted 2 sets of batteries for the oversight...an LED would avoid this dumb mistake.
I think Jin has given us a quality engine for the money... smiles per dollar are off the chart!
