Carbs too lean typically for that explanation.
what year is the engine ?
With the engine off and you put the throttle control to full throttle, do the throttle plates open fully ?
Is the timing advancing ? |

1985 the carb plates open fully as well. how would you check for the timing advancing? |

and yes the timing does advance with it at full throttle (carbs fully open) it only revs at around 2700 instead of around 5000. |

Was that always the case, or is this a new phenomenon? If this is a new application of this motor, you might have way too much prop for the application.
