Before messing with needles, closely inspect your
linkage to be sure everything opens & closes properly
on both carbs. One bent or out of allignment
component can mess everything up, and you'll never get
it right. I found this out trying to fix my front
choke. I bent the L-pin a little too much and messed
up my idle. Disassembled, started over and all is
well again. Just take them off, inspect on the bench,
closely, and re-assemble. Just a thought.
