Hey all, just replaced my old 462 with a 583 I picked up. 583 sat for several years (3 I think) without being ran. Got everything in and no spark at all. Replaced coil and wires and completely bypassed ignition/killswitch/teather etc. Im thinking the mag needs to be cleaned but figured id ask before I pull the flywheel and start on that. Sled is an 84 MX motor is from a 89 I believe but all the wiring was identical.
