    Numbers will be stamped on the dizzy base, you can determine type & suitability for your engine from that.
    Mechanical advance dizzy won't have the vac.can on the side - ( vac.can will be connected to the intake manifold by a vacuum hose.)
    I'm sure 1500king could rattle off 100 other identifying features, however these are the main two I'm aware of......
    Grab a Bently,Haynes or John Muir's & read up - lots of info in 'em all.
    Cheers, Mark

    You might like to read the novel we have going on here about my overheating kombi "Overheating issue... I fix one problem and another arises". Lots of info about how to keep your Kombi cool, including correct timing.

    Cheers.

    Yeah I did, changed the timing from 28 deg to 21 deg at ful rev.
    which changed idle from 7 btdc to 4 btdc.
    And it sounded better.
    waiting from response from 1500 king to lock up at that and test that over the next couple of days

    0231 168 005 is 021905205P...

    Can you take a pic of the electronic part of the dizzy?, particularly where the grommet is on the inside of the housing.

    Timing is 7.5 degrees BTDC with vac advance disconnected and blocked and at 875rpm. Engine revving with no load to 3400rpm should read approximately 40 degrees on the timing scale(7.5 initial, 20-24 mechanical, 8-12 vacuum). If not, then you have a problem.

    Retarding the timing will make your engine run hotter. If at idle and revving(with no load) to 3400rpm, total timing will reach approx 40 degrees advance on the scale.

    Then I have a problem as vacuum doesn't seem to be working .
    7.5 deg with hose on or blocked doesn't change
    But at that initial timing reved up gets to 28 btdc max

    hi, what is "locked up"? At idle, you shouldn't have any vacuum advance on. I just indicates that the throttle stop screw has been disturbed on the left carb. The throttle place gap should be 0.1mm, checked with a wire gauge, both carbs off(and holding the chokes open, no fast idles actuated). If any further open, your engine will start pulling vacuum on the vac can at idle.

    Have you checked the vac can to see if it holds vacuum? Vacuum must not bleed out of it.

    I see you have an old compufire EI... I went through two of them in my younger days before I went back to points... will never buy another.:rolleyes:

    Suck on it.

    The base plate will turn.

    Seal it with your tongue.

    Base plate will not move until you release your tongue.
