Lost spark, pulled cover off noticed the Pickup screw loosened (did not fall out) enough to let the pickup cover hit the Flywheel broke off the corner of what appears to be a cover. Put cover back on re tightened, re spaced, fired up. Question lies more around the plastic cover its there for a reason.....want to replace but all I found was non OEM. Are aftermarket all shit (like most elect) or doesn't the pulse/ pickup really matter?
