Dear Jayson;
I'm sure your correct.
My point is this; If the fuel isn't burnt in the first palce, the polluants arn't in the environment.
In 1960 the "automotive community" told everyone how to combat SMOG. They were ALL ignored by those with a vested interest in seeing the automobile "controlled".
The catalitic converter was 'sold' to Congress using (only) HC/CO 'numbers' from carbuerated engines at idle.
Since then; there have been so many lies & half truths piled on top of each other, that the facts are 'long gone'.
Recently the California Legislature passed a bill requiring a Cat on lawnmowers at a projected cost of $400 per.
This will never become Law, but you see my position.
At most of the meetings/hearings I attended (throughout the 60s) the ONLY intellegent thing said was: The pledge of alligence.!!
