I sent the question to Hobbico a few minutes ago, and we'll see what they say about their instructions. I checked the timing on my engine, it came set at 32 degrees BTDC. I reset the timing to 28 BTDC, which is the fully retarded position on the sensor holder. There is a very limited range of adjustment, and no way, no how, could you set it close to their specified 44 degrees BTDC. Thanks Milton and Ralph for confirming my thoughts on this.
