Running mogas occasionally with AFP injection and a purge valve.
It is my impressiont that mogas varnishes much more quickly than 100LL and consequently, I am interested in the purge valve position that most thoroughly drains the splitter, spider lines, and injectors so that the fuel cannot degrade there and create deposits.
I have tried it both ways, both open and closed after shut down, without any discernable difference in the sounds, smells etc. that eminate from the engine.
Maybe Don has already weighed in on this?
