Still working on slight tip in hesitation, getting there, but have some slow speeds around town bowl boilng to also remedy! Need some composite bowls! Heat shield not enough. Settled for the time being on 73 primaries, 10.5 PV, .052" PVCR, 83 secondaries.Aside from the above issues it runs great.

If you need a heat shield let me look around. There was one I was going to buy, but never got around to it. It seemed like the best deal at the time.

I've screwed with phenolic and wood heat shields and never found much.

Let me see if I can find that one I liked again.
