I did my redneck data logging AFRs on my new motor with the higher compression Alfaholics pistons. My first runs were with 135 mains and 220 ACs. That was to lean.
Then with 135 mains and 210 ACs which gave me [email protected]
and then 130 mains and 200 ACs which was [email protected] I decided on the 135 and 210. The pull in 4th from 2000rpm was smoother with this as well.
The complete jetting is:
135 Mains
210 AC
f11 tubes
34 chokes
55f8 idle
Ed and anyone else, what do you think. Also posting on my new motor thread.

The passenger seat is 15 miles an hour faster than the drivers seat.
