I have a motobecane mobylette I think its a 77 that runs alright, its a little slow to accelerate but it does eventually do it(I do think its because im a big guy, but even on the flats the acceleration is a bit sluggish from 20-25)
the problem is it wont idle. It did yesterday after me and thor replaced the throttle cable, and today it wont do it. I found out the spark plug I was using wasnt burning hot enough (black carbon deposits all over it, made it not start) so I got a new plug, but according to the guy at kragen itll work but I need to get a BH5K NGK spark plug.
The carb is in decent shape (recently cleaned) and Im wondering if the spark plug is the cause of the idle problem (I can live with a sluggish acceleration, it is only a 50cc engine)
