Ralph,
I followed those steps exactly. It worked perfectly on my work bench a few weeks ago and I just now got around to cooking with it. Today the servo sits and does nothing or vibrates. It moves intermittently but I didn't want it to fail closed and choke my fire. I disconnected the ring from the RD3 and am hand tuning it like a damper door for this cook. Basically I just set it to somewhere between an 1/8 to 1/4 open and left it. I should have bought the 4 pack of servos but It wasn't in the basically $0 budget.
