Tommy Very pleased about your engine - really, but not so pleased to tell you that you have broken the all time idiot record. Not by much mind you - you pipped out a few close contenders.
It pains me greatly to do this, but I will force myself in order to (hopefully) make a point. Please scroll down (all the way) and see how much utter useless Charlie Romeo trails below your few meaningful words. All this will now be archived for ever more. I have read some folks say - "Don't archive" - I am not sure that there is anyone sitting anywhere allocating each posting - I think it all just gets cast in. Why am I butting in? - Coz I would hate to see this group fall over due to some avoidable reason. Besides, ML is probably about ready for his bi-annual eruption - he really needs to spend more time in the Shop NOW READ ON, AND ON, AND ON.
