Question Super rich cold start

My '89 accord has been running fine for a couple months now. But now anytime i start it after it sets for at least a hour it runs really rich for a few minutes then its fine. Anyone have any thoughts? I just don't want to wash out my cylinder walls.

What was it doing before - wondering if related?

Does it seem to be choke related or is there "gas" getting into the carb when it sits?

I figured out the problem but forgot to post. My head gasket started to leak around cylinder #3 after I blew a hole in the thermostat bybass coolant hose. I tried a product called K-seal to try and fix it, so I poured the 8oz bottle into the radiator and drove it around for about 20 mins and that was almost a week ago... now it starts fine when cold and runs like it used to again . I'm honestly surprised it worked
