My compression test results

You ideally want the engine at normal operating temperature, so two minutes could've been not enough. But, the readings are consistent and that's really what you're going for. They're not as high as I would like them to be but it seems like the engine is just a little aged. Is it completely stock? Are you noticing a lack of power?

That, and the carb butterflies have to be full throttle wide open. All spark plugs removed. Fully warmed up, half hour at highway speed? Fully charged battery, good serviceable starter running at crank RPM spec. Dry test, then wet test, avg of the highest of at least two runs per cylinder, etc.
Compression test is a bit more complicated than it seems for accurate result. Those numbers don't look too bad considering. Mentioned in another thread, a vacuum gauge connected to manifold will indicate engine compression indirectly, and a whole lot more, with a lot less hassle. If engine draws 18, 19 or 20 inches steady then the compression is fine. A proper compression test itself is awful hard on the starter and battery imo.

It's stock and it's a project and it's not licenced for the road yet but I've driven it around the neighborhood a few times. I've got it all tuned up and it runs pretty good. Starts right up, idles good after warm up and revs up okay with no hesitation but when I drove it will fart at the carb a bit if I try anything beyond 1/2 pedal acceleration. Plan is body work and paint the exterior first. Phase two will be replace the tired drivetrain.
