    I had a good read of all that over the weekend. Unfortunately i don't have a vac gauge or tacho. So until I do, I have to make do with winding out the idle screw.

    Also I screwed the idle mixture screw in a 1/4 turn and it stumbled, so backed it out to where it was. Which I doubt be too far off.

    The vac advance definitely works as car is smooth as silk driving. I quickly threw the timing light on it at idle and it was around the timing marks so didn't fiddle with it.

      Really!?! That's insane! What's the timing spec at idle (and everywhere else apparently!) with the vac advance disconnected?

        Back in the day it used to be:
        Screw it in until it stumbles, then screw it out, counting the turns, until it stumbles. Then screw it back in half the number of turns.

        That worked with countless cortinas, escorts, falcons etc.

          Cool, learning new things every day. They say use a vac gauge and dial it back off stumble where max vacuum is. Idle should be 500-550 rpm in gear, auto.

          12deg btdc with no vac to dizzy

            With vac disconnected is no advance at dist no matter what the rpm
            ..or vac diaphragm has a hole..

            (That got me a beauty when ipicked up my xp falcon and drove back in freeway at 5 deg advance)

            Ford only 'loadomatic' system.
            Dist and carb have to be matched pairs as the carb has a 'spark control valve 'which shifted between manifold, ported and venturi vacuum - Depending on engine load to give vacuum to the dist to advance it.

            Ford used it from about 1958 to 1967 in australia for the 6s cyl. ( Straight from the usa)

            .....Was so good they changed to mech advance dist with vac trim -like everyone else.....

              Still got points? If you get a dwell/ tune up meter they can measure the rpm for you when you fiddle about with it.

                  Finally got around to tinkering on tune. Idle mixture was spot on and gave 17 vacuums. Dwell was spot on at 39 degs (recommend 37-42deg), idle in gear was down at 450 rpm so tweaked that up to 580 rpm. Also pulled the new plugs and they look spot on

                        Found an original xp horn from a mate for $20. Went up to wallan to get it yday. Gave it a clean up and works fine.

                        Front has settled another 10mm and height is pretty spot on. These have really weird body shape that slopes front to back. Interestingly it's apparent in the Thunderbird's.

                        Still have a weird random thing where it dies at the lights once in a while particularly when it's fully up to temp. Got me stumped.


                        Edit. I think I may need to pull vac advance unit and see if it's sticky. It looks all clean and new under dizzy cap, but only thing I can think of

                          #FordLyfe - Has the same issue on a XD and the Mustang. Fuck it's got me stump on the XD until a Ford Eng told me (well after the fact mind you) that the Earth straps to the block were junk. The Mustang one was aids and now has a massive 10mm thick copper earth strap. Seems to work as it doesn't stall when hot

                          On other cars it was the coil, check it with a multimeter when it's hot

                            Good pointers. I have a new coil ready to install (I left the original Lucas one there for originality but Fuck that). I have the battery earth lead go to the head but will check other earth to chassis.

                            I might go over the timing and check new plugs. I read the rotor cap shaft clip can get loose so rotor flops around.


                            I should add it only done it the last month since weather is cold

                              Found the problem. Vac advance diaphragm toasted. And mechanism inside dizzy was sticky as well. I'm surprised it ran well with a vac leak and locked timing. Ha. At least easy fix

                                as in hole in diaphragm?

                                if so you were running about at constant 8deg (or whatever you set the timing at).


                                a tip - blow thru/clean the metal tube to the carb -and clean the carb drillings with carb cleaner spray

                                i had same problem originally - changed the diaphragm - but still had no advance. turned out the hole in diaphragm had allowed the carb to suck dirt into the tube and carb drillings blocking them.

                                if new diaphragm can use a timing light . to check it advances before getting into the carb.

                                i 'think' you cant get full advance just free revving the engine- but you can see the advance working
