I have acquired an OLD K&B Greenhead .29 that I think I'm going to put on a RSM Ringmaster I'm building. I've run a partial tank of fuel through it on a test stand and I think it will be OK. I'm pretty sure It's been a while since this baby has been run, but it seems to have good compression, etc.
A couple of questions.
1. Suggestions for a prop. I ran it with a 9X4 and it seemed to do OK. I was thinking an 8X4 might let it turn up a little. It's my recollection that Torps like to wind up.
2. It has a restrictor in the venturi. Should I pull it out and let it breathe more, or leave it in?
Thanks guys
