not sure enrichment will keep the overall motor temps siognificantly lower, unless its REALLY rich.

Start from the beginning.

Replacement what?

Explain how you know its running cold, and how cold. Temps  from IR gun?

How do you knwo the t-stat is good - fairly common problem.

finally, is the coolant temp sensor good?
