Here is what did work: Load at 200 to 250 degrees, set the gasflow level at 2 and the airflow at the mark on the airflow rod, roast for about 3 1/2 minutes, (until the temp is around 330), then drop the gasflow to 1. At the first crack drop the gasflow to the pilot setting, about 7 1/2 to 8 minutes into the roast. Total roast time is 11:30-12:00. Keep a close eye on the Fluke during the period between the first and second cracks, you may need to kick it up a bit to prevent stalling. With this gas roaster, an increase in temp setting takes effect quickly.
The factory installed temp gauge is almost useless and trying to roast by eyeballing the flame level is more of a challenge than I am up to, so mods are necessary.
My Fluke K type probe mod is a bit shaky, but it works. I plan on doing something more permanent in the future, a la Ken Fox's sample roaster temp mod.
Installing a BTU gauge is a must, if you are going to roast by adjusting the gas rather than the airflow, (minute adjustments in the gas control, cause huge differences in temperature). This is a fairly simple mod and requires few parts. The challenge is finding fittings that go from metric to SAE and back to metric.
PM me, if you would like a parts list or specs on the gas gauge.
