What about my 1971 Gulfstream 165 I/L6, the RPM won't go higher then 31-3300 if I push it anymore it starts backfiring. But it will run fine all day in that range.

Changed the fuel pump, filter and lines. Before that I ran the boat until it ran out of gas to get all the old gas out, and then changed all that stuff. I'm looking for replacement carb.
