Go to your local Goodwill or Salvation Army store and get a crock pot (don't use the one your wife cooks in[] ) go to your local automotive store and get a gallon of antifreeze.
Put the antifreeze in the crockpot, remove carb. and any rubber gaskets from your engine put same in the pot set heat on medium and come back in about three hours the engine will look like new.
