Thank you! I put that plug in but still having same issue with mower starting but only running for a few seconds before it dies. Warmer it gets the shorter time it stays running. Appears I have a bigger issue
Can anyone help me determine what spark plug I need for a B&S 140 cc 550ex lawn mower engine? There is an Autolite in there now, but those are hard to find in my area. What would be the Champion equivalent? Thank you!
