I've already squirted Marvel Mystery Oil in the drivers side cylinders, guess it wouldn't hurt to finish the job by doing the passenger side... I've got a big paw, and even with the front wheels off it was a pain to get the wire's off and get the plugs back in. I only realized AFTER the drive home that to prevent the Ujoint socket from flopping all around while trying to position it on the spark plug tip that I could have just wound a bit of my painters tape around it to keep it 'semi-rigid'. Then it would give way once it grabbed and I needed to get it out of the head.
Again just my opinion...I like this stuff!
I helped a buddy who bought a Jeep get it running after ~15yrs.
We hosed the cylinders with this stuff, and let it sit for a few more days.
Fresh gas, fresh oil & filter, thing fired right up.
Smoked a little LOL, but he is still driving it, and it's not an oil burner.
I've seen guys just fire up cars that have been sitting years and not have problems, but I've also seen guys have a real oil burner. Probably from rust in cylinders and dry starting it scuffing everything up??
Even though a pain, I'd fog 'em heavily, @ least that way it's not dry, and if there is rust in there the stuff will help. It sure can't hurt anything.
Whenever we stored a car or boat for winter in MN we used this stuff. I believe it is worth the effort.
I once bought a '65 Galaxie that had been sitting for YEARS in a chicken coop for $200.
Carb was completely filled with crap, cleaned fuel system, rebuilt carb, and used a similar product. Changed all fluids/filters too.
Car fired up and ran good, again it wasn't an oil burner, and the engine was strong and healthy.
