    Don, heres an update.

    I ran the motor on muffs for about a half hour, and IKNOW I KNOW this is NOT how you calibrate them, but was able to reproduce the symptom. Motor starts and runs, bring it down to below 1500RPM (on muffs), and it started running erratically. Load up, drop a cylinder, then run fine, etc.

    Playin with the low speed adjustment had no rhyme or reason.

    So I pulled the carbs and replaced with two other ones and >so far< it seems to be running right and idling down lower.

    Im heading down to the ramp to run it on a test prop and will submerge that sucker lower than it should be to see how it responds!
