    Pull the heads and make a timing mark you can use the stop method like Brizy said on the other site but if you want it spot bollok use a dial gage up to you.
    I will back them up bout the new dizzy I played with some and heard lots of um run and its a very rare thing to find one thats got the right timing (I have a very keen ear when it comes to Fords lovelys!) Most of the aftermarket Flatty mallorys have way to much max advance and the advance comes in way to late. Ajustment for max advance on stops in the dizzy but to get it in earlyer yuo will need softer springs.

    get somebody with a snap on dial back digital timing gun to set the timing. Don't need timing marks, shows on the gun what you have, dial in what timing you want, watch the dial go to 0 whilst you move the dizzy and it's done.

    no idea, all they can really measure is rpm, voltage, advance and dwell, so somehow it works it out, you just hook it up, and it tells you on the dial what advance you have in it, to reset it, you dial in what you want, and move the dizzy till the dial reads zero.

    oh and if you can't find somebody with one, a bolt threaded into the plug hole can be used. Pull the dizzy cap, turn the motor by hand with all the plugs removed until the rotor point to where No1 ign lead would be on the cap. That way you know it's on the firing stroke. Thread the bolt too far into the bore so the motor locks by hand, unscrews the bolt in tiny amounts until the motor just moves past TDC and you're roughly at TDC. If you want to be spot on use a dial gauge on something floating but a good fit in the plug hole

    The ROTER BIT IS OK But the bolt bit don't work as its a side valve thanks for the info i had the heads off and got it spot on now just got to find out about the advance curve on the Mallory distribitor as i believe it may be the trouble !!!!!!!!!!!!

    Hopefully there should be 2 ajustable stops in the dizzy below the points plate ( or behind the points plate cus being mounted on the front) to limit the max advance loosen the allen bolts and movem allong the slot to ajust. Softer springs in there will let it advance quicker.
    Most Flatty Mallorys I seen have got lots more advance than required. 1 had 38 degrees in stead of 24-26 total. With a mild cam say Isky max1 or so on in a normal Flathead likes maybe 6-10 deg initial timing, slap on the afore mentiond dizzy and you get 44-48 deg total!! Not good for acceleration / power / rod bearing life.
    The main symptoms the car showed were poor power (for engine spec) poor fuel consumption and surging wilst at cruising speed.
    Thats my polite version of my Malory experiance. Cider will bring out a lot ruder and more grafic tale of woe, but I might get sued.
