The biggest issue you will run into is the if the magneto and flywheel have lost too much magnetism. If you have someone close to you or an old tractor shop around, they should be able to re-magnetize for you.
Easy test is if it wont hold a wrench or screwdriver across the armature, it will...
Showed this thread to a buddy and he mentioned that you need a blower carb or dual carb. Something about not pressuring the bowl. (its beyond me)
Maybe that would help?
