I would find a new mechanic....Originally Posted by tspear
I doubt it. I know I do not use it
Based on what a few mechanics have told me, one of the few uses I would try if needed is for a sticky valve. Fill the cylinder with MMO and pull the prop through to push the MMO against the valve and create a hydraulic lock; let it sit overnight and flush. The solvent aspect of MMO will sometimes fix this problem.
