Can Fouled plugs still spark when taken out?

[Braap257]

Just curious, As a couple of days ago i changed the oil in my bike. And started it up and just let it run for about two minutes since it had been sitting a while. But the trouble is that i shut it off. And later it wouldn't start back up. It had fuel. So i pulled the plug out it was a light brown and it was wet. "I know that means too rich. I'm still working on that"  But when i plugged it into the boot and kicked over it sparked pretty good? Can it still be fouled???

yes it will... get a new plug from your local auto parts store.

I didn't know they would carry the right ones. In that case i will pick up a few, so i can have spare ones for jetting

Yep get a BR8ES or B8ES. No need for the expensive EG series.

Yeah true that, you can get 3 for the price of 1.

Run the cheaper plug until you get the jetting right.

I use the BR8EIX plug and it lasts alot longer then the cheaper one's.
I dont foul plugs tho.

When my plugs foul, I just dip mine in clean gas, wipe it off really good with a wire brush, then with a cloth, then I take a torch and burn it for about 30 seconds, and it's just like new again.

Fouled plugs often have an erratic blue spark or a white spark.

Do you guys get NGK's irridium range in the U.S. ?

My '98 YZ250 will occasionally foul a plug within 30 seconds of a cold start, and that plug will never work again.  It may start after a good cleaning, but will always foul again right away.  Even when jetted correctly, this bike has always been very sensitive to plugs - it will sputter and cut out with an ES, but if I take it out and put in an EG with no other changes it runs perfectly.  I bought an Iridium to try, but haven't fouled the EG that has been in there all year, so I haven't tried it yet.

I love the Irridiums from NGK. I am always trying something new and thought plugs were plugs, I've tried all the BOSCH lines to those split fires and never really noticed a diference till I tried the Irridium about 6 yrs ago ofcourse they were like 12 bucks a piece the but now they are down to about 5 bucks, never ever fould one worth every penny and it feels like 1 extra horse power.

Yes, since the (basically air, even in the cylinder) gap's resistance to arcing increases with increasing (air)pressure. -Think compression.

Well the bike fired up fine today. maybe it got flooded? My friend is always coming in my garage and twisting the grips on our motorcycle lolz.

That would only flood a 4-stroke with an accelerator pump on the carb, shouldn't hurt a 2 stroke at all.

Is he always pushing the kicker down to feel the compression?
