So I found runaway really quick after I took the lock collar off the fuel screw.
There's a lot of turns that don't runaway but that really like to carry away the RPM's when you fuel it in idle. When you're a twist before runaway, the RPM's carry away after you take them to 1400 RPM, then they drop off real slowly when you get off the pedal. Then, as you continue to turn the screw down, the RPM that the pump carries itself away gets higher, and the drop-off time after you take off the pedal becomes un-noticeable.
I tried to turn it to the point that it maintained speed at all RPM's in idle; then I drove around for a while and noticed that I have absolutely no EGT problems. Then after I was driving it for a while and warmed it up, I took it to 2400 RPM in idle and noticed that it did climb a bit on it's own. But it fell right back down when I took the foot of the pedal.
So, the question is, where do most people stop? Do most stop right before it starts to climb away on its own, or do they stop right before the RPM's don't drop when you release the pedal?
Did my pump really start fueling itself because it got hot, or did I just not notice it before? If the pump loosens itself up as it gets hot, wouldn't it be possible to warm one into a state of runaway?
Since I have 1/4 inch of the screw left and I can still not hit 1250 EGT's, I have the feeling that I'm expected to tweak it farther...
