I just have never seen a serious knock that didn't keep knocking and get worse. Maybe something is slow getting oil to it.

I thought the same thing on number 1 and I think it is paper or paint but number 4 is definitely an arc from the plug.

My God Tim, how did you see that!? Definitely, you found it. The plug is grounding to the block. The arc is traveling down the electrode and across to ground on the block. We are hearing the fuel detonating in number 4. That plug must have a cracked center electrode. I had to put that up on the big screen to see it!
monty509, pull that plug either the center electrode is broken or the porcelain is cracked. I think TJ found it for sure.

Actually I BLEW it up like you did and kept hitting the replay on my office computer and sure enough it's a arc.
Easy things first. Great catch TJ!
The only reason I kept looking at the video was it didn't really sound like a rod,valve,wrist pin or anything metal knocking around it was more of a muffled sound like a misfire or something.
Maybe it's not the plug but it's a lot cheaper and easier to replace a fouled/broken plug then jerking it all apart.
Believe me I have heard plenty of motors have Scrap Iron Fits and this one didn't sound to bad at all!!:confused::confused:
I pulled the plug no real visible damage to it besides some small chips on the very to of the insulator. The plug has quite a bit of dry fouling though, maybe that's causing the ark, insulator not being able to insulate? We will find out Sunday when my gaskets get in and I put it back together. I got some new plugs. Maybe i'll put it back in and run it in the dark and see what it does. Thanks for all the help, very kind.
Also when I pulled it out there was a very strong smell of gas.
You are very welcome monty509, the smell of gas makes me think it may be the plug even more but the thought of running it in the shop/garage in the dark will be the answer.
