I have a mac 110 chainsaw that I am trying to repair. It belongs to the rancher whose land I deer and bird hunt on, he loves it and I'd like to get it working for him. If it were mine I'd toss it and buy something newer. None the less I have disassembled it and installed new plug, new points, condenser and a known good coil. Still no spark ? I have the following questions if anyone can answer them I'd be grateful. 1.) There are 3 areas on the flywheel that look to be magnets. The 2 smaller have magnetism the larger does not. Is the larger supposed to ? 2.) How do I know that the "kill" switch is not "off" can I jumper or bypass it ? Thanks for any help you can provide.
