Add one more thing to my on going quest to get a better idle.

After timing this thing to smooth out the idle I noticed something. First off the temp gauge in the cab will start climbing as the truck warms up, then the needle will jump up to the middle of the gauge, pause there for a few seconds and then bottom out. Bubble in the system? Oh and now the dang radiator is blowing fluid past the cap. I think the timing being so far off is causing some heat issues even though the truck runs fine and doesn't show anything outside of the normal operating temp once the guage rebounds.

Ideas?
