Post St-St-Studdering at take off.

The 951 seems to simply stutter at take off. If I just slam on the gas from a real real slow roll it'll stutter a tad before it goes. What usually causes a studdering take off other than motor mounts, because those were recently done.

misfiring will cause a coughing in the engine. timming. That has been my experience.. in engines that stutter under full acceleration.. Or too much air in the mix to cause a detonation.. possible vac leak...?

Tranny mounts are a more common source of stuttering. You can feel a slight "back/and/forth motion from the rear". Because the 120# + tranny "swings" on a deteriorating piece of rubber!!!
