Narrative:

At 200 ft AGL on final, the #1 engine rolled back. Landed with no problem. After pulling off runway 9 and taxiing in, I noticed the #1 fuel lever a little past halfway to off. On further investigation, found the spring for the #1 cutoff button to be very weak. I think the button might have been brushed by the first officer while he was silencing the gear silence horn on final. This button is right next to the cutoff switch. Due to vibration and the switch out of the detent, I think the start lever went to the cutoff point.
