Last thing I want is to have to drill, weld or tap a hole in my motor for a plug. These motors are pretty efficient on proper air fuel ratio. Any addition plugs are a great place for air leaks to develop which will turn these air pumps we call motors in to oil pumps which will pump all the oil out of your motor. Or lean them out and make them melt down. Both making it very bad on longevity of a motor.

Good luck with the banquet / meeting, wish I was a little closer to attend.
