OK, here's another one. It's actually pretty simple...
To get the obvious out of the way I've got a rebuilt to original spec engine
and head. Dizzy's rebuilt and I've got a new timing chain and gears. New
cam and valves adjusted to the paper that came with them... Lastly but not
leastly the carbs, (1 1/4" HS's) have been rebuilt...
Now that we've got that out of the way, the rear carb is the problem. If
you've been following the list I had an un-centered jet problem and year ago
I had seal problems, and both have been solved. However, with the
adjustment nut all the way up, (0 flats out) it's on the edge of being in
tune: the plugs burn black with just a hint of brown. Soooo, I'm looking at
needles now. Currently there's a standard, (ES) needle in it. Now if I
want to lean the carb out do I go with a lean needle, (an AP) because it
needs to be lean'd out or a rich needle, (an EM) because it's running to
rich?
I'm sure there's a Seinfeld episode in there somewhere, but as always any
help appreciated.
