    I installed an engine in my 1963 that I bought used. The PO said it ran fine and had low hours on a rebuild. Engine runs good but lacks some power. Engine is stock except for Solex carb. I couldn't seem to get timing set right. I run out of adjustment on the distributor. I installed a vacuum gauge and it reads 14-15 HG.

    Is the problem the oil pump not indexed right or could it be the timing gear is not set right? How do I tell?

    Would a worn distributor also cause a similar issue?

    Try moving all the plug wires around one spot.

    When I bought my '60, I found that some previous yahoo owner had turned the adjusting plate over and installed it wrong. Would not let me do a full range until I flipped that plate back over and got it installed right.

    Re-clock the positions of the spark plug wires 90ยบ where they emerge from the distributor cap.

    In other words set each wire back (or forward as the case may be) one position on the cap. Then try re-timing the distributor body in it's new range.

    Pulling the whole unit and resetting it with the drive gear one tooth over is another possibiity.

    BTDT :oops:

    There's a plate (item 17 below) with two slots in it that bolts to the bottom of the distributor, one slot is for the distributor bolt (item 21), the other is for the bolt that holds the plate/distributor to the block, if the plate is on upside down or the distributor bolt is not in the right spot on the the slot then it's impossible to get the distributor aligned to the right rotation orientation to set the timing correctly.
