I wish I had seen this tip last night JerseyMo! I acquired a Timex with this exact movement. The mainspring was fine in mine thankfully, but the thing wouldn't kick off and run. So I made the mistake of disassembling the little bugger. Like you I had a hell of a time getting the escape and pallet to stay in position until I decided to try backing the v-conic balance pivot away. Just like you, that gave me the room I needed to get everything in place. The balance still needed a bit of coaxing to start swinging, but it has been running uninterrupted all night. I took mine apart before I took any pictures of it, I will post some later today.
