MISSING! One spark Plug! 2012 Jonway 250 By dangerousdave (Read 1,994 times)

Amber alert on my 2012 Jonway 250 I can't for the life of me find the spark plug? I think I see the wire with a silver / crome end but if that's it how do you replace it? How do you get to it?

HELLLLLLPPPPPP!

If you have the 250b linhai/yamaha clone, here is where mine is.

[replyingto=richardthescooter3]richardthescooter3[/replyingto]I believe this is it the 257 but still dont see the spark plug location?

Look at Richards picture. He has his muffler and header disconnected but thats the general location where the spark plug is. Same for my 257 Roketa. We have the same scooter me and Richard.

I lightened the picture up and pointed to the spark plug.

If you have the VERTICAL 244cc engine, you get at the plug through a small hatchway under the seat. Tight fit, but doable. The plug (on mine, anyway) takes an 18mm socket, and I found a 1" ratchet extension helpful -- just don't drop the thing down into the bowels of the engine the way I did!

On the photo's showing the spark plug on the 54B horizontal engine, the photo appears to be from the right side of the machine.

The photo of the engine itself appears to be from the left side.

HUH!! Most motors have the spark plug on the right side of the head not the left side.

Alley, I think what bob was saying is that your pic shows the plug, since it's of the right side of the horizontal engine.

Richard's pic of the horizontal engine is from the left side, thus not showing the location of the plug.

Some youtuber made a video walkaround of his JCL. Around 3 minutes in, you can see where he cut an access hole into the plastic.

That pic is from my right side just above the muffler area, you just can't see the spark real clear that's why Alleyoop lighten it up to see it.

That rooster should be on the forum,he seems to have a definite opion-lol

OK Mr OOP, I was speaking in reference to the poster apparent confusion. Now I would like to wonder about your comment that all engines have the spark plug on the right side. I have seen small engines with the spark plug in the head and pointing down. I believe the 244cc engine might be in the back but am not sure as I have not checked on my engine yet.

I believe that someone had the right idea as they mentioned that I had noted that the engine photo and the scooter views were on opposite sides of the motor. Just my short version of getting to view the engine from the right perspective hoping to help the poster to find the spark plug.

Also noted Mr Oop, that you said most spark plugs are on the left side. Maybe so, but that leaves right side, front or back, and top for alternative locations. Just trying to be a help to the momentarily confused one.

And not all of the posters have spent their life working on small or large engines. I have done enough to know that all engines have personalities that you learn by working on them. I started by working on a 1937 Packard 8 cyl touring sedan. Now I have graduated all the way down to single cylinder engines over the last 60 years.
