Good morning all! I'm having some issues with a stihl ms 441... I bought a hyway big bore kit for it. And once I got it together I noticed there was a free port on the bottom of the piston on the exhaust side when the piston is at TDC. and now this saw is dumping fuel into the carb.. Is the free port causing this issue?? See attached for picture. Any and all help will be greatly appreciated! Thanks
