<< I have noticed that my 77B, which has a Weber DGV carb, has a
significant amount of sooty moisture which sprays from the exhaust upon
startup (with the choke on). If the rear of the car is close to the
garage wall, the wall is coated with black spray. It seems to go away
as the car warms. I am used to seeing some condesed water dripping out
a cold exhaust, but this seems to be somthing different. My wife is
tired of the black soot marks on the driveway. Anyone encountered this
B4? >>
Chris,
Do you take your car on a lot of short runs? If so this (the moisture) is
probably due to the car not being warmed up sufficiently, and is not
completely drying out the moisture that condenses in the exhaust system. The
black soot is possibly caused by the carburettors being a bit too rich, and
the combination gives you "wet black soot".
Short runs will also cause your exhaust system to rust from the inside
quicker due to the moisture.
Just my $.02
