I was going to attempt it my self but where I think the problem is there is 3 parts. I have no spark. So if those 3 parts in the handle wasn't the problem then I would be just guessing on the problem. Coil????? I was told I was 54 in line.:doah: Pretty busy place. Its just not mini bike parts, They also have a Stihl dealership and sell other mowers, etc.
