I leave it at factory settings because I don't want to lean it too much while not properly broken in, causing the engine to heat up too much, with subsequent deadsticks. ...and because the manual says to leave it at factory setting in the beginning. Also as posted, the engines runs very well, with no hickups and minimal hesitation, despite four stroking a bit at the low end. I just want to protect my "$1500 - 5000 plane" from deadsticks and have a well responding engine. Not that much of an engine geek.

But, if you head did not fall off you shoulder from shaking it , could please post your oppinion if you think the amount of goo is from running too rich or if you think this level is normal even for a well adjusted engine in the process of being broken in?
