I played with the spring again and I think I have it right now. The bowl doesn’t have that pesky drain which can leak so the leaking might have been because of a fibre washer I placed between the nozzle and the bowl. It didn’t seem necessary there so I moved it to the outside under the bowl nut. Now the bowl seems to be tighter on its seal. I’m also betting the McCulloch crew built this motor early Monday or late Friday as the carb cover decal isn’t very straight! 😀
