  • Exhaust popping
  • To begin with, i very seldom have to ask for help here cause i get most of my answers reading the board and the how toos sections.plus almost 30 years of running and repairing these little tractors. And many thanks to the masters on this board!!!
    With that said, i have a popping noise through my exhaust. I read an article on, I believe this site, about the different popping noises and the rhythm. Popcorn, Intermittem popping. Backfiring is from dist. But only did that once.
    Back at the end of I did a complete tune up. Pulled dist. and cleaned it good. Fly weights were stuck. Installed a new sediment valve. Now have that popping sound and cant find that article so does any body have any idea where that article maybe

  • I would look for an exhaust valve that is stuck or not seating. Do a compression test while the engine is hot see if it points to one cylinder.

  • Does it sound like this? Maybe you could accompany it also. . . .

  • Does the "popping" correspond with engine RPM?

    If so, you may have a burnt exhaust valve (could be stuck, but much less likely).

    Is the power noticeably down?

    Do a compression test. A dry test is adequate to identify valve problems.

    If you have a single low cylinder and the "popping" corresponds with engine RPM, look for a burnt exhaust valve.
