It is a #4-40 nut. Thanks to Bob Archer who answered my request.

I lean to roughly maintain a constant EGT after about 1500' MSL. That's not a lot of leaning and definitely not LOP, just conservatively maintaining the over rich setting used for a sea level takeoff. Once at cruise, usually 7k to 10k, I maintain WOT, reduce RPMs to MP minus 1. That is if I have 23"MP then I set RPMs to 2200. Then go to LOP. This gives me between 150 to 156 TAS with a burn of between 10.5 at 10k to 12.2 at 6k. Other notes: I have started to reduce RPMs to 2600 after takeoff because it just feels more comfortable. I used to use 'one notch' of flaps for TO on my soft home field and 0 on hard surface. Now I just use one notch in all situations. I climb at 0 flaps and go to reflex when reaching cruise altitude. On the ground, I try to maintain 1000RPMs or better at all times to keep lead fouling at a minimum. Thanks for asking the question - I am curious too.

I climb full power 2700 rpm due to terrain. In cruise i have been using 2300-2400 rpm and usually about 21 in MAP at 8500 msl.

I'm based at SL and I see about 27.5" on takeoff. I wish that was higher. When I'm clear of the traffic pattern I reduce RPM to about 2500. I use the %HP indicator on my engine monitor to tell me when to lean. I know 75% is the rule but I usually start leaning below 70%. Once I'm in cruise-climb I reduce RPM further to about 2250. My engine doesn't peak nicely so I just pull the mixture until it's too rough to live with then richen it up til it runs better. Even then it still misses occasionally but not so badly that I can see it on the EGTs or anything--just some minor roughness. That usually nets me a cruise of 160KTAS on 10.0 to 10.7 GPH. I can go a little faster for a little more fuel, a little faster still with more RPM, to about 165 at altitude. But I usually don't. The power setting I use just seems comfortable. I depart with flaps at 0 and retract to reflex at the first power change.
