I saw someone recommended putting MMO down the spark plug holes and letting it sit for a bit to help that clean some valves, although i'm not sure that's it.

Also, when i was running the sea-foam spray through it the knocking was steady at the rpm i used (in the midrange) and then when i started spraying the knocking went away for about half the time i did the treatment. If it was something like a rod, i wouldn't think that would make a difference at all??

I feel like i'm missing something simple that would make a lot of sense.
