Re: Which of these engines is the best? Ordering now.
The SD Stinger is the best engine I have ever used. Very good casting quality on the head, 415 chain, NT Carb, and they respond to emails and will send you a new engine if the one you received is defective.
NOTE: they are currently switching stock to a slant head style engine. If you want to receive the original SD Stinger with a straight plug head, you have to ask for it...
