I'm running an FA180 on glow fuel, but it has CDI. I know you said you don't have the time or energy to do a "conversion" but just going CDI is a lot less complicated than a full gas conversion. It will take less than 1 hour W/a CH-Ignitions system.
The FA180 responds very favorably to CDI making a little more power & getting 25% better fuel economy than glow ignition W/the same 15% glow fuel. I have done comparative
TESTS FOR FUEL CONSUMSION & POWER OUTPUT W/a stock FA180 GI, a stock FA180 CDI & a high compression FA180 CDI.
Starting & general user friendliness is improved dramatically & kick back is totally eliminated. Just something to consider.
THIS VIDEO shows just hown well mannerd the FA180 is W/CDI/glow fuel. This is a high compression version, but the stock FA180 W/CDI behaves just as well if not better.
