Long story short. I’ve got a 25hp Johnson I’m trying to fix up. I tested compression 120 in each cylinder. ( I was bogging down at full throttle) I rebuilt carb , replaced fuel pump and lines. Etc etc . I also replaced spark plug (stripped the second cylinders threads on accident)
Current situation is the motor will start but die immediately (5seconds) . Would a spark plug that isn’t fully torqued “seated tight” cause this issue ?? Would it cause low fuel pressure? Trying to understand if I’m on the right track
