Dear All,
Carly has started to suffer from a peculiar problem. I'm pretty sure
that the problem is in one or both of the carbs (SU HS4s), but I can't
for the life of me work out what is causing it, or how to fix it. Let
me explain...
Once at operating temperature, taking the car out of gear (or putting my
foot on the clutch) no longer immediately returns the engine to idle
speed. Instead, the revs drop as they should until they hit about 1500
rpm, and then slowly creep down, taking 30 seconds or more from there to
idle. Putting the car into first gear and letting the clutch out for a
moment whilst stationary allows the revs to drop swiftly to idle speed,
except in the hottest weather, when the problem is (a) more frequently-
encountered and (b) impossible to cure. Mileage has dropped by nearly
15%.
All the linkages are running freely; the carbs were cleaned out a few
weeks ago, when fresh lubricant was added to the dampers, and a fuel
filter added to the fuel line.
What's going on? Please help a confused and frustrated mechanical
ignoramus...
ATB
