power valve size

Thanks Brian6pac that’s the kinda info I was looking for. I’m not sure why it ran for so long the first time an then fouled out so quick after I messed with the carbs. But I was wondering about the pv size I just wasn’t sure exactly how the ref pv manifold pressure thing was supposed to be working. I’ll order some new PVs before I try it again and go from there. Really thanks again for the info.
