Definitely give it the throttle! Don't baby it past the first 5 minutes.

I'm impressed with the little engine. It runs smoothly (so far) and fairly quietly. It sounds like I'm riding my chainsaw! I'm running stock plug wire and plug and built a wiring harness for it; therefore, shorting / grounding potential is minimized (hopefully).

A good plug/wire/cap will do you a world of good...try it, you'll like it.

The gears make the characteristic whine. I'll try a wee bit of grease as I've seen in some posts. The chain is stretching; gonna have to take out a link soon.

Lithium, or white grease is best, don't get crazy with it!
