I wasn't saying the Troll would overheat if you ran it on gas - just that engines running gas generally run hotter than running petrol.
I turfed the standard fuel pump and put in an electric one
as soon as you flicked from Gas to petrol, the pump started to pump

mine was a 1989TB42 carby
I had a Sprint Gas mixer on the top of the carby
electronic ignition
extended rotor
silicone plug leads
and lots of other goodies
was tuned for Gas performance, as it would only go into Petrol once a week

but I could switch from Gas to Petrol or Petrol to Gas on the move - alot of people seem to have trouble switching from one fuel to another
