I need to move a 770 gas that has been sitting for a few years. Engine was free a couple of years ago but it has sat with the carburetor off since then with a rag stuffed in the bottom of the manifold. I was thinking I better squirt some witches brew into the cylinders before pulling it into the shop to install new carb and fuel tank. What do you experts mix up or is there a ready made product? Last time I tried to soak cylinders I used Marvel mystery oil, gas line anti freeze and some penetrating oil but sadly the old 400 cu in her did not break free so can’t say I have ever had a successful treatment.
