Been having an issue with my OptiMaxx. It’s not making full RPM.

it’s getting to about 4900. I change the plugs, changed the fuel filter and it’s no different. It started to produce quite a bit of smoke yesterday. Pull the plugs in if you’re looking at the motor from behind it, the bottom left cylinder spark plug was drenched in two-stroke oil.

How would one cylinder be soaked in oil?

I put a spark plug tester on that cylinder and it’s firing off appropriately as well as the other five.

I also put brand new wires on for good measure.
