Mod E70ELCNB would start good and run fine but at WOT it would run for 10 minutes and then bog down to around 2000 rpm's. I would throttle back and after a few minutes it would take off and run fine again. I did a spark test and # 2 cyl. had no spark at a 7/16" setting. I changed the ignition coil and was still the same. Pulled the plug apart fron the sensor coil and checked A to D was 16.9 ohms, B to D was 24.9 ohms and C to D was 30.1 ohms. I think this is the problem but would like an opinion before I pull the flywheel etc. as I would have to make or borrow a puller. Thanks
