Default Re: Model A Missing Badly

I had a similar problem that was caused by sticky new stainless steel valves and guides . It has been said that using new stainless steel valves with new replacement, original style valve guides can cause a sticky situation . After adding a liberal amount of Marvel Mystery oil to the fuel solved the problem . I now mostly add four ounces of Marvel Mystery oil to each ten gallons of gas that is used in the car .
