    no time to adj, don't ask
    2. shuttle strap on 4,5,6,7,8,9,10 all good.
    3. rebuilt shuttle rod
    4. checked shuttle height(is set at AMF specs)
    5. no the shuttle is not square
    6. changed cup tilt tie rod(2-612)now the
    cups hit tops of pin on respot!!
    7. gap between table & shuttle is twice
    what it should be.

    I personaly would start there. If you have a cycle counter on, take it off. Drop the back 2 support rods, and bend it back and forth till it is square. then go tighten the clamp studs on the front.

    I like my shuttles lower than the book sais.

      This is a double pin release to the cups, not a double cycle of the shuttle.

      When the shuttle releases the pins to the spotting cups. The belly of the first pin entering the cup must be high enough to hold the upper pin in the bin while the shuttle closes.

      Crank your table through a spotting cycle and when the spotting cam follower is in the low dwell of the cam check the pin bellys to see if they are up enough to hold a pin.

          Move your table back and set it up at 8 1/2" from rear to spot,this means when yoke is re adjusted the pins will need to be moved forward to put them on spot.By doing this the angle is flatter under the shuttle and the pins fall flat, and not at an angle, into to cup.This will stop the tips of the cups hitting the heads of the pins.If machine is too high them the travel arc of the table is more and the shuttle opens when the table is nearer the pindeck, allowing the posibility of double shuttling (letting two pins through at the same time).I hope this is a little help for you.
          good luck.

            I bet if you lower the machine to 18 3/4 to 19 inch's off the pindeck and you re adjust everything they problem will go away. The gap from the table to shuttle is to much.

            It takes me an hour to lower a machine and make all adjustments. Just had to lower ours because of new lanes being installed and the machines run so much better with them being at the correct hight.

              keep in mind that the book adjustments are for brand new machines, and dont account in years of sanding and lowering. a 30 year old center has the table farther away from the bins and shuttle. If no one has bothered to adjust the entire machine height over the years (and believe me, I have seen this hundreds of times) then your guage is of no use on the shuttle. JMO

                I found one time that I had where the cups were hanging up the shuttle. You might wanna check to see if you have any wear on the cup fins that will be a sign the shuttle is catching the cups.

                  One thing I did to try to solve this without readjusting entire machine height and everything related, was to drill new holes in the brackets that the rear of the bin hangs on. One between the original holes and one just below the lower one and remount using the new holes. This lowers the rear of the entire bin and shuttle around 1/2" closer to the table. Was the easiest solution I found, until I could acutally go in and do the entire machine height adjustments.

                  Worked on 90% of my problem machines.

                    I agree with the man from Scotland. I have done this also.
                    Yeah but, We've always done it that way.

                      Yes, I agree. Maister is the Man!

                      With the front of the machine sitting at the correct height off the deck and using the 8 1/2 inches table pull back rule your shuttling problems will soon vanish!

                        If the machine are too high I increase the distance of the shuttle to bin accordingly.

                        In really bad cases you can lower the back of the bin assy buy relocating the rear support brackets.

                        I just learned about the 8-1/2 inch trick with the table from Gerry from the UK, have not tried it yet, but in my next class........
                        Please.....follow the instructions!!
