How are you checking for spark? Open air tester or spark plug head against ground in open air? I have checked for spark with plugs and got good spark in open air but absolutely zero fire under compression with fuel / air in the cylinder. Are you using new spark plugs? My first thought was reversed spark plug wires as was previously mentioned, but I bad plugs is another possibility. If there’s no fire with directly primed cylinders I suspect no spark under compression.
