Hi all. Cub Cadet 2146 with the 14hp Linamar (Onan) engine. Will crank and run but spits back out of the carb at idle. Seems to level off at higher r.p.m. but still pours gas out of the carb. It has a Nikki carb that has been taken apart and cleaned.
I checked and adjusted valves to .006. I would like to check timing but can't find the timing marks. Any help or idea on why I have the back fire, spitting gas problem would be appreciated.
