I am not sure about your 61 but on some earlier models like my 52 the needle will bounce around a bit and act crazy. If you catch it in time a good lube will work wonders. The earlier ones had a "wick" to lube them and they dry out over the years.
Before you do anything be sure to "measure twice, cut once".
