If I were you I would toss in a bnib .28 like an lrp and call it a day, sounds like a classic case of a used and uncared for engine, verry verry common, we hear and se it every day,...a loose carb will create an almost untuneable engine, you can seal the engine up and give it another go if you like, you will need a tube of the copper rtv,
