drive chain doesnt fit on sprocket?

alright, so i got around to putting the drive chain on the moped im building yesterday, and for some reason, it wont fit right. its THIS CHAIN right here, and im 98% sure its a puch sprocket. i dont know if i bought the wrong chain, or if the sprocket spacing is off or something. you can see what im talking about in the picture below. has anyone else had this problem? if youve got any solutions let me know, thanks.

Are the sprockets also new? If not, the sprocket teeth may be worn out.

sprocket is worn OUT

Re: drive chain doesnt fit on sprocket?

its weird though, the teeth look fine, not worn or anything. oh well i guess its time for a new one

Measure the width of the sprocket

415 chain is 4,7mm with 7,77 rollers

420 chain is 6,25mm with 7,77 rollers

428 chain is 7,85mm with larger 8,5mm rollers

looks like the ass gear is for the 420 chain which will work on a 415 gear.
