150 black max wont go over 3000rpm

[heiko592]

i have 150 black max that won't go over 3000 most of the time. it is smooth and isn't missing, and sometimes it will rev on up. it has new plugs in it and it did it before and after the plugs. somebody thinks it is the switchbox or stator. i used a timming light on all the plug wires and i don't see any missing. any help would be great

If it's not ignition then it's probably a fuel problem, fuel restricktion to engine or dirty carbs.
