All the old Fox's were run with Castor oil which is what probably made the engine seize up. The easy way to clear that (and also minimize the residual coating inside the engine) would be to heat it up with a heat gun while trying to turn it over by hand. You might find that the little nipple on the muffler is plugged with congealed oil also, just push a common pin or small wire thru it to clear the blockage. Most (if not all) these old Fox's run very well but do like a castor based fuel of about 20 to 22% oil.
