works great
Put this on a commercial wood chipper and it pulls like it should. Electric start is smooth and the 3A coil handles the battery charging without any trouble. Definitly buying Honda again.
fired right up
We keep a couple of these on hand for equipment swaps. Quality is what you expect from Honda, and Northern got it out the door fast.
Runs well and starts easy. The box had a small dent when it arrived but the engine inside was fine, so I can't complain too much.
