A compression test will verify how bad the engine is or isn't. The NAA, dunned the JUBILEE only for the '53 Model, used the new Ford 'Red Tiger 'OHV 134 CID engine - a much better design than the flat tops. The 600 Model was introduced in 1954 and also used the 134 block. Later the 800 Model was introduced and they now used the OHV 'Red Tiger' 172 CID Engine. Cylinder liners were cast iron since mid-1950. I suggest to get the block stripped down before buying any new parts. You will want to take it to a reliable shop to get boiled before rebuilding. they or you if doing the work yourselves will want to have it checked for cracks and get the bores verified, crank ground, and possibly other parts in order to see which parts you need. OEM 134 bore spec is 3.44" but some have bored out to a larger size and piston and/or discarded sleeves and bored out larger too. Get yourself a copy of the NAA Operator's Manual; a copy of the 39-53 MPC; and a copy of the Clymer I&T FO19 manual. The other important facts are how is the electrical system? Is it running OK now? Is it OEM 6V/POS GRN or switched out to 12V? Sheet metal can be replaced -Dennis Carter makes new repops and ebay always has parts for sale. And you can always repaint any colour you like. If you got the unit as gift then you don't have much investment in it so evaluate what it would need.
