Don't give up on that heater yet! Actually, just the presence of the 7" to 6" reducer is enough to disrupt things. This heater is just sensitive as heck to any disruption of the air flow. I tried putting a bit of duct in the out-bound flow, and got unhappy sounds from the flame, and it turned orange. However, with it blowing into the open cowl and the suggested sleeping bag over the top and closed side, everything in the engine compartment was warm to the touch in less than a half hour, but nothing was hot. Setting it up on a chair was enough to do that, even at the 30,000 BTU setting. Ambient temp in the hangar was 30 degrees at the time. It must have worked on the inside, too, because the engine started in two-blades. Took a good long time to get oil pressure... ...I guess the stuff in the gauge's tube was pretty thick. And I had a 'miss' on the left mag until things got hot... probably moisture. But after 10 minutes of ground running at 1000RPM, the needle was off the 'cold' peg, and after a couple of full-power run-ups, I had 140 degrees. Good enough! If it's too cold for that to work, well, it's probably too cold for this guy to be flying in an Ercoupe.
