This circa 1850 movement has been rebuilt by me. In testing it stops right before the warning as the strike train tends to creep and jams the strike detent against the edge of the slot in the strike wheel. In order to avoid the hammer being on the rise, allow for warning run, and have the clock strike all the hours correctly there seems to be little room for error. Is there a procedure to follow to set up this time train to accomplish all these objectives? I will now attempt to attach picture files, I am better at clock repair!

additional info on my clock: There is a hoop wheel which receives a square shaped lever to stop the strike. The lever I have shown is the detent strike lever. It is on the same arbor as this hoop wheel stop lever mentioned previously. This detent strike lever is the one that gets jammed in the slot of the count wheel. It is radial to the count wheel. The count wheel is driven by a pinion on the strike no. 1 wheel arbor.

I know the problem. What I always do when assembling the strike train is put in the great pinned wheel and the second wheel and the hammerlever and locking lever. I arrange the great wheel in a position when the hammer has just fallen of the pin to struck the hour, hold it in that position and then have te second wheel position arranged so that the locking lever has just falling into the cut out in the hoop. Then keeping them together with a tie rip. Then the third wheel with the locking pin 180 degrees away from the warning stop. After assembling the movement in this way, there's no abstruction problem with the countwheel. (if the countwheel detent has not been bent improperly)
Good luck.

After utilizing the suggestion from P. Hageman I found it helpful to ensure that the hoop wheel lever was in the far end of the slot, seen as the hoop wheel rotates toward the lever. As well, on closer inspection I noticed a small arrow between two of the teeth on the count wheel and a slashed leaf on the driving pinion. Once these two marks were aligned, the strike detent lever remained free of the oncoming end of the notches on the strike wheel.
