Unburned fuel into the exhaust? Maybe an ignition wire is bad.

If you can use a multimeter, each wire can be tested for conductivity using the resistance settings.

I would not think so, since fuel must be getting into the exhaust.

Have the wires checked, including the sparkplugs, sometimes other branded-sparkplugs are not matched with the engine. Try to look at the fuel lines also.
