Honestly I've never had fuel or carb issues (knocking on wood) with quality OPE.
I do run stabilizing additive and a tiny splash of TCW-3 in my E10 pump gas... and try not to inventory too much.
When able, I'll run them dry. Dry is probably relative, Ive never pulled the carb to see if it's truly out of gas. Ive always wondered if doing thst leaves just enough that it can evaporate and leave residues, while if more gas was in the bowl, it might not evaporate out...
Regarding fogging, I've bought fogging spray with the best of intentions. And come the end of the season, I either don't remember, don't have time, etc. is my stuff worse for wear? Not that I can tell. Maybe if it was stored outdoors it would be an issue. It's not.
Is it best practice? Guess so...
