Hello Pat I ran the posa and it performed well at top end and was difficult to dial in a happy medium for the rest of the range. I had a Zenith and sold it before flying with it. Others like it. With the posa, no fuel pump is needed. Carb heat is always a good recommendation. As for the 29, I don't have a clue. See my alert Posa page on my web site.
