In CT, MGBs with emissions gear fitted struggled for years to pass
emissions testing, which was performed at an idle. Four or five years
ago, the test was changed, to a 35 mph (approx) test in top gear on a set
of rollers. Suddenly, amazingly, everybody's MGB passed the new test
just fine----with or without the emissions gear!
So, it can be said that one could, with clear conscience, remove the
air pump, the air rail, and other plumbing. One would like to think
that the new test more effectively measures pollutants at actual
operating conditions (else why would the test have been changed and
expensive new testing equipment installed?) so that the MGB passing the
new test meets or exceeds the spirit of the law, if not the letter.
My MGB has the evaporative fuel system in place, since I imagine that
by trapping vapors for future use, it may be saving a tablespoon of fuel
each and every year. That system has no effect on the engine's
performance.
