This is my first post on here and I'm hoping people will be able to help.
I got a 1972 Garelli Bimatic moped as a barnfind last September, I pulled it apart with the intention of repainting it to match my beetle!
Anyway I finally got the engine running today (after months!) and it starts and idles really well. However, it doesn't rev. If i open the throttle it just gets louder.
Then my wife pulled the (not sure what to call it) clutch/.starter lever (The one that you pull so the pedals engage the engine) and the engine sped up and then responded really well to the throttle.
It revved beautifully but only when that lever was pulled!
Any ideas why this is happening, I dont see why it should make a difference!
