I believe due to few miles on for several years the compressions are ok.
The vacuum gauge with 20" at idle is good and if it were me I would continue to drive as is and attend to whatever comes along. If idles ok, carb and condenser and coil ok and it starts ans stops ok on the brakes thats good for me. Possible carb gaskets may have dried out with sitting.
All the best.
