Now will un-adjusting the smoke screw (fuel under low boost, right?) help ireduce egt's while just cruising around at low rpm, allowing the it to cool down a little faster,? Could it have anything to do with the oil? (shell 15w40 Rimula, just switched fr/rotella)
thanx, ian

If you turn the starwheel down, it will fuel faster when boost comes on, up, slower.
