Just put a new carb on my engine. ? is about at what rpms the power valves should open. Max rpm is 4900-5000, 6.5 power valves in the primary and secondarys, 74 jets squared, engine vaccum gets to 6.5 at 4500 rpms. Is this the correct opening point for the power valves or should they open sooner?
is this the 750cfm dominator u were going to buy?...if so...leave it alone & run it...good to go out of the box
