2004 kymco mongoose 50 No spark

Recommended Posts

I have a 2004 kymco mongoose 50 two stroke and it was a mess and it didnt run when I got it. There was practically no wiring harness and all of the wires that were there were electrical taped together. Long story short I ordered a aftermarket wiring harness (Complete Wiring Harness Electrics Wire Loom Kit CDI Rectifier Ignition Coil Magneto Stator For GY6) installed it and now I have no spark. Any ideas or help would be greatly appreciated.

Did everything line and bolt up ? Stator coil ? Kill switch included in the kit or did it plug right into the harness?  Also the 50 cc atv’s have the rip cord shut down safety on the rear is that connected ?

The new harness came with new everything, stator, coil, rectifier, kill switch, cdi box the whole works. Everything plugged right in, most of the new stuff bolted to the factory locations. I never found anything for a rip cord. I finally go spark last night but not in a conventional way I suppose. Now that i have spark i tried to start it and it keeps flooding itself. So I adjusted the float and now it's not getting any fuel. Also when trying to start exhaust out of the carburetor really bad.15691720495593691804897636076143.thumb.jpg.13a41dc78aeb06241196b1c3d7810e3c.jpg

Maybe the float level was right when you first took it appart, it may have been dirt not letting the float needle to shut right , try to readjust  float level as it was before blow all passages with air and it should work fine again.caburetors are happy when  cleaned thoroughly . How's your spark plug you haven't mention it through out the entire post they're also happy when cleaned or much better when new. Nice ride BTW,that frame looks neat!!

I re adjusted the float last night and cleaned the carburetor again just to make sure. The spark plug is new. Pulled the reed valves out and one had a piece of gasket maker in it forcing it to stay open. Put it all back together and still nothing. I am getting fuel and spark, but the spark is looking weak now😡.

Ok make an old school trick to discard possible trouble  sources when igniting motors. Pour a dab of fuel through spark plug hole, screw the plug back in and whith full open throtle try to start it over.Now if that doesn't work ,now you know fuel is not the issue ,it's got to be a spark problem ,  keep on posting the results I'll be aware of your findings. Good Luck !!

      I've cleaned the carb.still didnt fix.any suggestions?

      I just bought this thing and got the carb all cleaned today and it was running like a champ. There was a spare hot wire hanging down that was not hooked up to anything. I found it when I took all the covers off and did the carb work. Unfortunately I forgot it as well when I fired her up after cleaning and replacing the carb. While I was running her, the wire was lying across the exhaust pipe. The exhaust got hot, melted the insulation and next thing I know I see sparks flying everywhere Bike immediately shut down and all lights went off. I have nothing on the console now when I turn the key over. I fear I have fried my ECU. I found one fuse back by the box, a 30 amp, but it was good. Are there any other fuses on these things? Is there a way to test the ECU? Could it be the rectifier or voltage regulator?

      Hey so i sold my 04 rubicon and wanted something new so i went to NC and bought a '13 scrambler 850XP LE EPS.  love it the only issues with it when i bought it were a leak in the front tire and the mice had chewed through one of the spark plug wires.  currently have a substitute hooking the chewed end to the ignition coil so itll run on both cylinders however im having an issue finding a replacement coil wire for it and was wondering if yall had any advice.  i need the longer of the two coil wires and i can only find the shorter one online.  will throw up some pics of it when i can

      I am working on a friends 2006 Suzuki LT-Z50 that they purchased not running. I took apart the carb to rebuild it and someone had already been in there... They really destroyed the Air/Fuel Mixture opening in the body of the carb.. It is in no way repairable.
      I have not been able to find an aftermarket carb to fit this model.
      Does anyone know if an aftermarket carb is available?
      Thanks for any help.
