As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

ignition problem? Fishing for opinions (non Suzuki)

Folks,

My wife has a Korean scooter that doesn't like to keep running. It spits and sputters to life, runs a few seconds, and dies. I pulled the plug and looked at the spark, and it's pretty brown and wimpy. Not the hot blue I'd expect.

The opinion I need is this: which is more likely to cause such a spark - a failing coil or a failing electronic ignition module?

My thought is that if an ignition module isnt working, you would have no spark, so I would guess the coil is the most likely problem.

Or maybe just a fouled plug. If it's a two stroke they will foul plugs even with tuning set up perfectly.
 
The plug was in surprisingly good shape, but I cleaned it and reset the gap anyway. The battery was newly charged, too.

The thing was running fine about 3 days before, but when my wife went out to start it she ran the battery down cranking it. (Hence the new charge.) I managed to get it running and started around the block with it but it kept cutting out. That's when I started digging for a problem and discovered the weak spark.

does it have a resistor in the plug cap??? or is it a resistor type cap check with an ohm meter,also some plugs can be shorted down in side the insulator most common on two strokes , start with a fresh plug in the correct heat range
 
Is it a two-stroke? If so the plug can look fine and still not be good enough.
