I am replacing the carb on the wife's 78 superbeetle vert and I noticed that the interior of the intake manifold looks rather...... shall we say.. Unclean :(
It looks a little rusty (strange since it looks to be made of aluminum???) and looks as if the paint on the interior is chipping off.
Is this normal? I dont see any loose debris or obvious trash, but I am concerned that this may affect performance or engine life somwhat.
Anybody seen something similar? Should I be overly concerned?
Thanks Jim
