actually running it cooler as you suggested at around 220 instead of 250-270 before I shut it down today was loosing pinch/turning over easier/running super smooth. It just wanted to go to the 250ish range but by leaving flush would drop down to 220's while running. Then this afternoon everything was going good then out of the blue went to crap like another air leak. You know how they want to rev up as they get hot? Go lean thats what happened. But you were right the more I ran it the better it got.
