Well I'll be sure to double check next time. I've never had a clip break in any of my other motors before and it's just kinda crazy I get 2 that blow with less than 2 gallons combined. I would think if the clip wasn't in all the way, it would of came out during break in with all the extra fuel going in and all. I pulled the pin just to look at it and both ends are severely worn. That's something I've never seen yet either. You'd think this thing had 10 gallons on it.
