Columbia Payout Issue

[Biggym]

I am having a payout issue with my Columbia Twin Jackpot Bell. For instance, if I have 3 oranges for a 10 coin payout, the coin in the vestibule drops too soon leaving a 2 or 3 coin payout and a jammed coin magazine. I am unable to figure out the issue, need advice.

It looks to me like the coin-drop out of the vestibule into the carousel is timed to occur just before the payout sequence, so, I'd say you need to advance the coin-drop, not delay it. Now, I'm not claiming this is good practice, but in the past I've adjusted the coin-drop timing by tweaking the vertical leaf-spring doohickey behind and to the left of the escalator: bending the steel strip forward a little should make the coin drop into the carousel a little earlier in the cycle.

The article below is the best description I've read explaining the sequence of operation for a Columbia Mechanism.

Yes, and the guff about the leaf-spring is discussed in the second-to-last paragraph of the article; it tells you that the doohickey can be "adjusted" but doesn't tell you exactly how... I've just been bending it.

Thanks for all the replies to my payout issue. Taking "Marsonion" advice, I took apart the "doohickey" (Coin Shutter on Escalator Side Arm) and removed 2 small leaf springs that sandwiched the main leaf spring. The slot immediately paid out perfectly and did not jam. Interestingly though, I have another Columbia that also has the main leaf spring sandwiched between two small leaf springs but it has never given me any problems with the payout or the jam.
