Maybe you haven't seen enough engines with fixed timing [8D] 28 degrees BTDC is optimal timing for full throttle on almost all engines..There is only one company selling engines that are not timed this way, and by now maybe they changed...
Myself and C&H have been re timing these engines and increasing rpm by 6 to 800 by using 28 degrees....
Hand starting a fixed timed engine is not difficult, just get a big leather glove and flip it like you mean it....Been doing it for 20 or more years....
All my G26 conversions are fixed at 28..I can't tell any difference between that and one with syncro spark....I HAVE tested them both ways...
