I need help troubleshooting a balance complete. I replaced the balance staff, because the top pivot of the original was broken. This is my first attempt at doing this. Now the watch won't run. The balance oscillates for a few ticks but then stops. When i replaced the roller table, although i tried, i did not get the impulse jewel aligned with the mark for the original position (see picture below). Is this enough to cause the balance not to oscillate? Or what ramifications might it have? Thank you for your help!

Hi all doing my very first full repair on a balance staff/wheel assy. which includes removing the broken staff to replace it, roller table to re-shellack the impulse pin, clean, poise, truing, etc etc. After i removed the bad staff I noticed in the balance arm bore looks kinda ragged. my questions are: do I take a jeweling reamer or broach to remove those or proceed with staking the new staff in and prepare for riveting? 2nd question: looks like the old pivot measures .12mm and the new one is .13mm will i need to remove that extra .1mm? i'm thinking I do but all I have is a Levin pivot polisher, a few ruby and steel burnishers. I have no lathe. pic #1 shows the burrs.
