Hey guys I got my FCR running very well. Runs amazing, But, it starts great cold. Don't need the choke. But most of the time when it's up to temp and worse when it's hot, it seems like the engine tries to kick back when trying to start it. Anyone encounter this? It's a 39 FCR with 168 main, 45 pilot, and 3rd clip NCVQ. It"s never done this with either the stock carb or the 450R carb I had.
