I'm going through my logs today and notice my deccel is very lean 17:1 what can I do to fix this ? My VE is showing 43 wich i'd think would be adequate for low MAP and deccel...
also, i just have a thought that is kind of related, i wonder if fuel should be completely cut for long periods of time for engines that are running on premix? lubrication might become an issue after a long period of fuel cut...
in any case being very lean is fine when you are at 0% throttle decel.
The jury is out on the fuel cut while premixing issue. I've heard that it does matter, and I've heard that it doesn't.
I premix and don't cut the fuel completely. It's pretty easy to keep a little fuel going in and still lube the rotors--that's why at real low kpa's my fuel table has real low ve's.

I premix and do the same - 25K+ miles and no problems yet, excellent compression last time I checked!
lubrication issues may present themselves as long-term problems, not short term...
in any case, it seems that putting a small amount of fuel on decel if you premix is a good idea, just to be safe, as long as it runs smooth under that condition.
