[Lost and Profound]

So doing a bit more work on the 53 Lincoln. Car has been sitting for 20+ years, cleaned cables, new battery, car now turns over. I think its a normal speed for a 6v, but no expert on that, boosted with a loose 12v battery was a bit faster but not a huge amount.
No spark. New points and condenser, now have spark.
Carburetor stuck, seafoam outside and in bores, let sit carb and choke now move freely.
Unhooked fuel line as didnt want to suck in whatever sludge is in tank, spray fuel from bottle down carb. Doesnt fire, not even a hint of it.
Pulled out one of the plugs and hooked back to wire just to make sure spark was getting through and it is. There is compression coming out of the hole, not sure what the compression ration is one this engine, seemed like a fair amount but not as much as some higher compression engines Im more familiar with.
Any ideas what to do/check next ?
