New cat and muffler, timing is dead on. Just seems to run hot. Thanks for the info on the temp sending unit. What i replaced was on the intake between 2 and 3 (i think) in the water path. But not where you say it is, probably why the problem still exists. Any easy way to reach it without a blow torch? Does anyone know what normal water temp is for the 22RE? That would be real helpful. Thanks again all!
