how can i get full throttle regulation on an engine running 100% hho? would it be better to regulate the amps for the generator, or have some kind of propane demand regulator setup minus the air/fuel mixer? has anyone here got a small engine running with full throttle regulation? with a propane setup i would think a small tank to hold some hho would be needed to maintain a working pressure for the regulator. i have read that hho can be compressed a bit.
