Great input Dusty! If youre at all wanting to hone in on how the engine is performing from a fueling standpoint throughout the RPM range, an AEM AFR meter is a cheap means to do so. I am not at all surprised that you ended up stepping up the main jet as that was one of the issues I had at 6000 ft where I currently reside. Good addition to the conversation!

In regard to the mention of EFI - I definitely agree that EFI is a way to go if youd like to have an almost plug and play system. For a majority of people flying behind a ul or older ULS, it doesnt make sense from a cost standpoint to put a few grand into a fuel delivery system. that my .02 and im POSITIVE there will be those that do not agree with that sentiment.
