1983 Yamaha floods and will no

1983 Yamaha floods and will not start after cranking engine for approx. 15 seconds. All 3 carbs were rebuilt last year. New plugs. Same results. The engine will start if it sits in the sun to warm and I don't use the choke. Spark plug tester shows no spark going to any plugs. My manual shows a Pulsar coil test at the CDI. Leads across white/red to white/yellow shows 357 ohms (in tolerance). Leads white/black to white/green indicates 359 ohms (out of tolerance). Have I found my problem or do I need to check something else before purchasing a Pulsar coil? Thanks in advance.

"Pull the stator and spray with elektra clean, or brake cleaner if you don't have that. If it's dirty it could be grounding out."
