No ground needed. I got mine wrapped about 3 times around the positive connection on the coil. The wire connection behind it. Then push it up tight so the rubber insulator covers it slightly.
I don't know if anyone else has this issue. But the rpm do vary. Jumps up and down slightly. Few hundred rpm on idle. But still works good.
For the price, the trail tech works great. 5 stars. Had same one for 4 years. Been sitting out in all kinds of weather. Still keeps kicking. If gets real wet, might be little glitchy. But it will dry, and works great again.
