How do you rewind the recoil spring on the recoil start? I’m working on this motor for my neighbor and have it running pretty good in the tank but I made the mistake of taking the recoil mechanism apart to clean and grease , and the spring unwound. I know there has to be a simple way to do it but I’m not having any luck. I managed to carefully take one off a 7_1/2 hp Elgin and kept it wound all the way thru the transplant just to find out the gear is different. I’m hoping to swap the gear out by pulling the flywheel but I’d still like to know how to recoil them thanks
