valve adjustment and repair

Run to the parts store and buy Marvel Mystery oil, 1 qt and Chevron w/ Tectron injector cleaner. and a filter. Put 4 qts. of regular oil and 1 qt of MM oil. Run on high way for a few hrs and drop oil, and filter. do this until you clear out the sludge and then try Resoline with the same ratio. Use Premium Amoco and Inj. cleaner a few tanks and that also should make the engine stop knocking. In the old days a qt of kerosene and running the oil for a minute would flush the engine out of gunk. Plugs s/b changed too
