Popping backfire & sparks?


LawnSite Member
New prob this one has got me concerned! When starting my lt 166 v twin iv got popping so I headed bock to garage to investigate then I heard a scraping sound and sparks from the front of the engine. I still havnt figured out my carb issue only runs at %100 throttle I gave up on that one .iv checked my valve adjustments they are set at .006 as told push rods fine. My question is did I set the gov arm right? I loosened the terms then turned the rod all the way to the right while carb at full throttle. A video said turn it the same direction as the throttle arm. I hope I did that right if not can cause damage. Any tips appreciated
