I even had the valves checked. Engine shop says compression is 120 on one side and 90 on other side. They say it could be a bent rod or something with the cylinder wall?? They won't know the cost to correct until they go into the motor. Don't understand why it would have run great after coils and plugs and then revert back to a dead cylinder? The plug on the right side isn't firing but when I pull the plug with the boot still on, I see the sparkplug firing? Just hoping someone might have some knowledge of another culprit to my issue????? I have a 2012 SKAG Cheetah with 420 hours on it. I would greatly appreciate ANY help.
