Re: [DML] STILL running a little rich...??

["Jake" <jkampho@xxxx>]

Andy,

This was the exact same symptom on 6683 (was Rich's, now Mark's). Provided
the CPR is functioning properly, it might be the mixture. Turns out, it was
just flooding a bit at start-up. I'll bet if you rev the engine up past
that "choking point" and hold it for a few seconds, the problem will go
away faster. After Marty backed the mixture off a bit, the problem went
away.

I'll let Marty or Rich jump in here. Will you at the Midwest Connection
tech day this year? --I'm sure there's a place near there that could
analyze the mixture.

Something to consider, anyway.
