I DO agree that there really needs to be some sort of carb heat for a
center mount carb to work right. Sitting out there on its own, it's
going to stay cold, and in cooler weather it WILL ice up in damp
chilly times. Trouble is, there's not really any easy way to plumb
the carb plenum for anything that's likely to bring it real heat
unless you have one of the plenums that DOES have a chamber for that
sort of thing (some did) and perhaps you can run pressurized oil
through it... which requires additional plumbing. Been there done
that, not a lot of fun and it still takes a while to get any heat to
the carb which is constantly trying to cool itself as long as the
engine is running. I've seen dew condensing on the runners of a
warmed-up engine in damp chilly weather. And, I've seen an AFB (the
450 cfm variant)with frost on it, idling... rough.
Of late, I'm almost of the opinion that the best way to use a
4-runner intake is to put TBI on it, with the associated
electronics. Carbs work best when parked on a hot intake
manifold/log. That's how they were designed to work, at least most
of them anyway.
