    I like the air tool sound effects, I do the same thing but I make the noises myself, kind of like when you're a kid and you make the motor sounds when you push a matchbox car around the floor. 😆

      Yup, they are very common to leak vacuum out of the diaphragm. So not only do you not get your timing advancement but you also get a fairly large vacuum leak which amplifies issues on acceleration.

    My vacuum advanced the internal adjustment failed, the diaphragm had no leaks. The advance would overtime would change, and the 351w would start to detonate. After this video I adjusted the advance and two weeks later It was back to where it was. I never would have thought of it without this video.

    Good Morning! So glad you referenced proper vac hose to ported vac source. On my new Holley 4160 750, It would plug into the "timed spark vac source" on the choke side of the primary metering block but I run a MSD pro billet mechanical advance which I installed a curve kit. All timing in by 2500 rpm. Question? would C-6 trans vac line be manifold? Mine originally was to that ported "timed vac source" which I have plugged. Thanks for the video! Please leave a link to buy that awesome electric screw driver you use. lol Cheers from Motown.

  • @BB-gi1uv

    Back in the day there was only one vacuum source (manifold vacuum). The way we set initial timing was to remove the vacuum advance line and plug it set the timing and hook it back to the manifold source. The vacuum advance at idle gave the engine good initial response and the crushing vacuum will be the same at a given speed with ported or manifold vacuum...all vacuum comes from the same manifold vacuum when cruising.
    PS. The car might run hotter at idle with the ported vacuum.

    My vacuum hose coming from that advance is up against an A/C compressor mounting bracket. It is pinched. I want to put a right angle(90) fitting there. Do you know the size of the hose? I'm new this hobby and don't know the size of it or how to properly measure it. Thanks. Keep up the great vids.

      @AlfsMustangGarage  2 роки тому +1

      Well I'm afraid I wouldn't know either. Ford did a lot of different variations and I don't know what you have. You're best bet is to take that hose and fitting into a parts store and see if they can size up what you need.

      You would use manifold vacuum for a power brake booster or a transmission shift modulator or a PCV valve. There are many other things but typically not used on a vacuum advance unit.

    Great explanation, thank you, Alf! I just replaced my advance can, but the engine is still a bit unhappy. It's a 351 windsor, A/T, with the autolite 2100 2V, all stock except a pertronix ignition. It's got good power when taking off, ok power in 2nd gear, but at around 50 mph in 3rd it feels weak when accelerating, especially uphill, rpm goes up and it feels like torturing the engine. I wonder if that's rather a timing issue or carburetor/fuel related? Do you have any other idea where I could look? :)

    manifold vacuum is better! mechanical advance adds timing as you press down on the gas. vacuum advance adds timing under low lode poor cylinder fill do to part throttle operation. you need more timing at cruse and idle. the later years 1967+ had a vacuum swich that had 3 ports manifold, distributor, carburetor that would swatch between manifold and ported. ported make for a hotter engine that uses more gas good emissions. on manifold runs the engine runs 10-40 degrees cooler. it will idle better and you will need no choke as the idle speeds up as soon as it fires up. this is how modern engines control timing start with low timing and advance it at idle with minimal idle air. set the primary throttle open one screw turn from 100% closed warm engine with vacuum advance disconnected adjust timing for Peake vacuum then retard timing for 1/2-1 drop in vacuum if you can not get a defined peak adjust distributor for best running then adjust mixture screws for max vacuum then readjust timing for peak then dip 1/2-1 inch of vacuum or ware the idle speed is no to fast or slow. on stock v8 with 4 inch boor 20-21* degrees of timing is ware they run best most the time. check timing with timing light & write down the #. then set base timing to 6* then adjust adjust canister to bring in the amount of vacuum advance that gives you the timing you wrote down on MANIFOLD VACUUM. this is the best way. if you have a 5.0 or 5.8 efi with the spout connector in check timing at full temp it will be 20-21* at idle base timing is 10*. the computer is the equivalent of the vacuum advance.
