Hello, today i was out did around 25miles at once on my SR50R and then got to the pub and let it rest for a while once i started it up it was fine and i attempted to get home a quarter of the way home the bike was like spluttering and lost most of its power so i pulled over to give it a rest and then it would not start up, once i managed to get it running once i pulled back the throttle it just cut out. So i got my Dad to run back home to collect the correct tools to check the plug and a used plug which was still working tho. So i pulled the plug out and it was all black so i checked for a spark too and there was no spark from either plugs. So currently my moped is in a random persons drive as i got permission of them until tomorrow where i must try to fix it by hopefully just a new plug. Im thinking it could be the following things: The Carb being too rich? Having too high of main or idle jet? the Spark plug (Currently using BR9ES ngk plug) The Coil going on its way out? Or even the stator? Any help is really needed and appreciated! Cheers Brad! Any questions just ask!
