It's me again, I have a question for the smartest Cub Drivers anywhere to be found. (no brown nosing intended ;D). Just had that Stromberg on my C90 rebuilt (I know ya'll heard this before) and we are fine tuning it. The idle mixture adjustment, which way enriches it. Screw it in or out. It is now hard to start and gonna try enriching the idle mixture. Can anyone shed some light on the art of fine tuning these little carbs? PS: On a C90-8 Thanks again.
