Here's the deal...got caught up in the temperature thing...make a couple of laps...check the temp...too hot...richen a little...then a little more...oops, truck's runnin' like crap...

Well, this motor digs life at about 300 degrees, starts to come alive at about 265, at 297 nobody is hanging with me...about 320 it'll start to lean & I'll richen it or let it cool a bit...

So I ask you, at what point do I toss the friggin' thermometer and go with what my ears have learned?
