Thanks for your replies. I usually check my plugs in the reflection in my
knockoffs from the light from a Coleman lantern. My current needle supplier has
not suggested anything other than the RH, usually he has a plethora of
suggestions.
I didn't build the engine but it has an advertised compression ratio north of
10:1. It has an Isky cam with the number at home in the file. Previous owner
ran an couple of races at altitude (+- 5000 ft.) and one Kastner Cup down at
about 800
ft..................................................................................................................................................................................with
the SM needles.
I plopped the RH needles in at Blackhawk and it still looked lean. Hopefully I
haven't done any damage.
Bruce pulled well up above 5000 revs, I didn't dare venture up to 6000, but he
felt like he would go there no problem.
I'll be at Road America with at least as many needles as spare
spokes......................
Cheers, Henry Morrison, Albuquerque, NM

compare the profiles of RF, RA, RB, RC. these are
from lean toward rich, RC is the richest.

I think my engine wants more gas than is being
supplied by the RH needles. Anyone used another
standard needle to accomplish this? The carburetors
are the H6.
