I have a 94 evinrude 115, e115tlerc. it pops at idle and sometimes will not idle at all, runs fine or better anyways above idle. compression on all 4 cylinders was between 115 and 120. ordred carb rebuild kits, installed and same symptoms. while running with muffs on i used a temp gun and the lower port cylinder was about 10 degress warmer than the rest.(lean condition) i sprayed carb and choke clean around lower head area and idle changed, smoothed out. i pulled head and what i believe is called the bypass cover. gaskets looked fine. is there anything that is common or that i might be missing. also when i pulled the plugs before i did anything i pulled the plugs and they were all nice and brown no indication of lean. and previouse owner had dissabled oil injection and had been premixing gas.
Thanks in advance
Jeff
