Symptom 1. Initial start and take off are fine. Second time it bogs down when I quickly throttle up to get on plane. Back off and idle up slowly jumps on plane and no problems. Generally only does it on second take off.

Symptom 2. When idling looking at my graph I noticed it felt like the engine was lurching slightly. Almost like the prop is lopsided.

Symptom 1 showed up after the kill switch was pulled on plane. Put my hat under me to keep it from blowing off and caught the kill switch. Three trips since this has happen and the bogging is still there.

Symptom 2 I have no idea when it started, just noticed it.

Want to get it fixed before it potentially causes worse damage. Any clues?

Thanks

Ign. Coil failing? Carbon buildup? Stator going out? You might need to simply put a fresh set of sparkplugs in because when the kill switch is pulled fuel keeps going.
