Is there somehow a coolant temp correction? Heat has the biggest impact over anything else. My motor runs good until it gets warm then it goes lean. I am running methanal so it tends to evaporate alot more the hotter your motor is. Any ideas on this?

That would be the warm up enrichment settings. You need to dial the motor in when it's hot, then come back and set the warm up enrichments to their final values.
