I put a lot of trust in your expertise, Graham. I don't know why mine jetted at 69, but I worked my way up to it. Maybe I need to lap my decomp. I was super green when I put my Bravo together, and maybe a little paranoid and didn't want to seize. I worked my way up in odd sizes Un till it four stroked, then down a size. It runs great, and tops out at 38 so I left it. Haven't touched it since. I'll delve into it deeper when it's turn comes up on the bench.
