If it has variable exhaust ( the round dome type things on the front of the engine ), those could be extremely dirty and are unable to move. If this is it, buy the new gaskets for it, take them out, and clean them up. When you say compression is good, it must be at least 100psi in each cylinder ( 125psi per cylinder means perfect compression for that sled ). In most cases, under 100 psi in the cylinders means time for a rebuild, and if one of the cylinders is significantly lower than the other side ( even if your compression numbers are still high ), it's time to take the motor apart and take a look.
