My '78B has twin SU carbs; I've been having intermittent (but always at
inconvenient times) power problems; it more often than not happens on the
highway when it's being given some gas. It falters, and slows, and will go
like that for a few minutes, then will magically recover and be fine
again. It seems to be a fuel delivery problem.
I replaced the fuel filter; it originally seemed to make a difference on a
quick test drive (about 10 miles @ 80 mph, no problem) except it faltered
at the end.
I then used GumOut, and the car liked the octane boost, but it wasn't long
before it was faltering again.
Now I'm looking at the carbs; I've no experience cleaning these (they've
been on the car about 2 summer's worth). I unscrewed the top "bowl" or
whatever it's called, on one of them, but it looked spotless inside. If I
was to clean "gunk" out of the carbs, is this where it would
accumulate? If so, I'll check the other one (I only wanted to fool with
one at a time). I don't want to screw up the carb settings, so how can I
safely clean them (or make sure they're not gunked) without screwing up the
tuning?
I can find articles on tuning them, but not on cleaning them... any
suggestions?
Thanks
