Probly needs a decoke and a shade of ignition advance..that keeps the
valves cooler. Set the gap correctly, and then loosen the distrubutoir
and
rotate while idling until it start to slow down, then set it as far
advanced as possible without slowing..a shade of over-rich also helps
keep
the valves cool.

Running rich helps the petrochemical smog too.
They all need scraping or at least banning from urban areas along with
other
heavy polluters (not CO2) like buses.

I think that buses should be banned, period.

How about banning roads and working class as well.
