For the sake of future requests and to feed the archive. It is a #4-40 nut.
Thanks to Bob Archer who answered my request.

For the past 280 hours, I generally takeoff and climb to cruise with WOT
and max RPMs of 2700. 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.

Bill,
I have been using neutral flaps on my 5800 ft runway. if Rw less than 3000 one
notch of flaps. 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 depart WOT, full RPM. 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.
