Yes-
Fans, I have that ill '74 that I rerouted the vaccum lines according to
TRF w/ the new fuel traps and now can't get the car to start (ie. catch).
My '74 has four ports, which goes where I have no clue. My mechnic is
on extended summer vacation, waiting for him to return to get problem
resolved...the summer is almost over).
