I use a small O.J. bottle (12 oz?) with fittings glued into the cap. I leave it on the test stand at a high idle of about 2500 rpm for an hour to hour and a half with occasional partial and full throttle. If it burns 3-4 oz per session that's a lot. I don't know about running at full throttle, but I will next weekend at a fun-fly. Building an alum. muffler, mtr. mt, and prop adapter for this event. Also puting on a JEH ignition setup. I'll try to get some good results and post them ASAP.
