    Setting timing with no timing marks

    I've set the timing on the Ranchero best I can (it runs & pulls well) and tried to set it with a strobe, but it seems like the timing marks on the balancer are in the wrong place, the strobe isn't picking them up (they're painted white).

    I have no idea why (yes, the strobe is connected to plug number one) so is there another way of setting the timing without using a strobe?

    You need some sort of reference even if you a test bulb and not a strobe. Find true TDC and adjust the timing pointer to the timing mark and go from there.

    When I set it up initially I used a whistle in No.1 plug hole to find TDC but was concerned that wasn't accurate enough to time it properly. It's all a bit odd as the balancer is perfect and it runs well....... I'll use the whistle again to find TDC tomorrow and go from there.

    Every day is a school day, what do you mean "used a whistle"?

    As already said you will need a static reference point.
    Take out #1 spark plug. Get a length of fairly rigid plastic or rubber hose that will fit into the spark plug hole. Make it about a foot long so there is no way in hell it will drop into the cylinder. Turn the engine over while holding the hose until you feel it being pushed upwards by the piston. When it stops moving upwards rock the engine back and forwards a few times until you get the exact point that the hose stops moving upwards. Make a mark on the crank pulley in line with your reference mark. Now continue turning the engine in the same direction until the hose starts to move downwards. Again rock the engine back and forth until you get the exact point the hose starts moving. Make another mark on the pulley. Using eyeball and guesswork make a mark between the two previous marks. This is your true TDC.

    I used a rubber pipe that was a tight fit in the plug hole and pushed a whistle in the other end. When number one was on the compression stroke the air was pushed out of the plug hole & through the whistle, when it stopped whistling it was (near enough) at TDC.
