Power_Man Posted July 14, 2016 Report Share Posted July 14, 2016 did you do have the cards off right before this happened? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted July 14, 2016 Report Share Posted July 14, 2016 4th clip from flat end Sent from my SM-A500Y using Tapatalk Okay. First thing to do is make sure the slides are in the correct carbs. Is it good gas? Clean correct plugs? Ratio correct? Have you done anything to see if you can fix it Quote Link to comment Share on other sites More sharing options...
