so anyone else experience this? I been chatting with moss motors and they really havent been much help. I plan to go get a dyno run and see what my A/F ratio looks like cuz I suspect I am running rich. Stock JR FPR with the fixed 5:1 rising rate has been known to run extremely rich on many applications. A car running rich is safe, but performance isnt exactly ideal. Let me get your take on this.
