Well i finally got a plug reading, put in a fresh plug and got this. To me it looks a little rich. But i wanna get some more input from ppl that have seen more of these than i have.

Whats with the fancy plug? Looks a tad rich, BUT, did the engine idle at all before you cut it off and pulled the plug? In order for a plug chop to be accurate, you need to kill the engine at high rpm WITH a load(assuming your engine if on your kart). That means taking the kart for a ride, killing the engine at speed, and coming to a stop without the engine running.

Yea thats what i did. I pulled the motor off the kart after i pulled the plug, thats why the motor is on grass. I plan on doin a little painting.

Try the stock E tube till you get the other exhaust. That 140 tube dumps a lot of fuel into the engine, and that weiner tube exhaust does not let it flow enough.

Can't see porcelain around center electrode. That is where color should be checked.
Also, why the multi gap plug?

I had some lying around from a previous project that got destroyed in a fire.
