Hello everyone I recently bought a 1977 Motobecane Mobylette with 680 original miles on it. I am looking to get it running but as of right now all it does it back fire a tiny bit every now and then. It has spark and compression. I was looking at doing the timing next. But while I’m waiting for the puller from treats does anyone have any other advice? I’m hoping timing is the issue. I have never worked on a Motobecane before and fortunately I found one for dirt cheap in insanely nice condition. I truly believe this one will be a runner soon!
