The fellow with the sagging problem, what size prop are you using? It sounds as though you might be "falling off of the ports", even if a pipe adjustment doesn't make much difference. Sorry I have forgotten your name. The old memory ya-da-ya-da-ya-da. (smile)

I've seen pattern fellows having to use 11x6 or even 10x6 props with certain engine/airplane combinations. In fact, I own and fly a G60 Bluehead that absolutely howls and hauls the mail while spinning an 11x6 prop, with a Mac's open front muffler. Every so many years, one of the top fliers that I run into scolds me and tells me to change it to something a bit more stout in pitch. Sometimes I do, and I'm always disappointed. Back on goes the 11x6, until I forget again. Yes, this is definitely "old school".
