I have replaced,trigger,stator,switchbox, plugs and coils. Ive disconected kill switch at the switch box followed cdi trouble shooting and still no spark. Compression is 150 on both cylinders. Starter turns the motor over just no spark. Its started and ran on the hose 2 weeks ago and the next day had no spark. Any ideas would be greatly appreciated on what would cause no spark would be appreciated. Thanks
