I just finished breaking in the Dle 170. Right off the bat I noticed the carb would be dripping fuel and have dry plugs. I went through everything and it was all fine so I commenced to flipping again with the same wet carb dry plugs. Then I went to the DLE website and read the manual, it says "briskly" flip the prop through. So, wondering if maybe I was too slow for it I grabbed the drill with the 3" cone and it started right up. It starts great with the drill but I can't get it to by hand. Just some food for thought.
