Check the vacuum line to the petcock. Manually apply vacuum to the petcock with a vacuum pump.
Check the battery voltage - before cranking, during cranking, and running at idle and 3000 RPMs.

I'll give all of these a shot tomorow, thanks for the suggestions. Brilliant idea though, enrichening the mixture by use of the choke would be far simpler than changing out the jets. Completely overlooked this idea, thank you for saving me the potential work.
What makes you think it could be the petcock vacuum line though? I'll give it a shot but I'm just curious.

The needles looked just fine to me, I certainly didn't make note of anything out of the ordinary. What exactly did the wear on your needles look like? I never even knew wearing out needles was a thing at all, never heard of wearing out needles before.
Also can you clarify about the use of rubber caps for the valve syncing? I'm not quite sure what you mean by that. Are you referring to a valve clearance adjustment or a carburetor sync? Either way I don't ever recall using or even seeing any rubber caps.
