Hi Paul , not sure how to free the 2 arms up, pull the starter off and see if you can get them moving a bit better, bit of oil in under the pulley may help. I just put another pull starter on. As for not starting, I have a procedure for testing if it has been straight fueled and if so it is only good for spare parts, not worth repairing. This is always my first step before wasting any more time on them
