Bought a 77 Piaggio Bravo yesterday and the PO had replaced the head due to a broken CR spring. Now I am a complete virgin when it comes to mopeds and the CR deal is new to me.
Will the moped only start with the CR lever in (valve open)? Will it not start or just be difficult to start with the CR lever out (valve closed)?
How much throw or lift is there to the CR valve? The cable and linkage is kinda sloppy and the lift looks just minimal.
I ask because I have a no start problem and I'm looking at service history and operating theory for all possibilities.
