When I was young (a long time ago
) & more lunatic about fast cars, than I am now, I had one that had been modified by the previous owner.
I won't bore you with the detailed techie stuff 'cos I don't understand it
). Anyhow it had been fitted with twin carbs, plus enormous air inlet ports, direct into the cabs.
On several occasions, it suffered from carb icing. This was usually when going over high ground. The only solution was to slow down, to decrease the effect of ram air into the carbs. On a couple of occasions I just had to stop, & leave the engine idling (which was all it would do) & wait for the heat from the engine block to melt the ice.
YES, I learnt about carb ice from that car!
(But it did go like s*** the rest of the time
)
