hello i have a 1973 auto and i have replaced all fuel lines, filter, cleaned the manual pump and valves its a low mileage car 23k so not worn? absolutely all electrics have now been replaced.
the car was stood for 24 years so there was a little residue in the first carb and it had a sticking float (all good now)
as i have thouroughly cleaned it (have not had a chance to do the second but this would make it run lumpy and rough surely if something was amuck??) it runs nicely and smooth but its still running very lean and only gets some oompf when the choke is pulled the majority of the way out. The carbs are capped off at the mixture screw so myself or the prevoius owner could not have fiddled??
nothing is missing ie pipes and there does not seem to be any gaps around where the carbs bolt on though there is a loud whistling when accelerating hard this i thought to be air whistling in past the elbows going to the filter?? or is this something more sinister?
is this a common fault?
ps what is the correct grade of oil for the dash pots i have looked through all my manuals to no avail, it has a very light oil in them at the mo as it did not seem to like 20/50 which is what the marina su's state.
so any suggestions on what i may have missed would be appreciated.
Cheers Keith
