I'm assuming there is a standard direction for these carbs. I can't give you a serial number at the moment, and the meager documentation that came with the beast isn't explicit on the subject - it just advises to lean until the RPM rise is 25 to 50 when leaning to cutoff. Thanks for any help on this.
