1977 Vespa ciao piaggio running bad

It ran great one day then wouldn’t run but for a second then quit. PO’s exhaust was welded together and came loose so I figured That was issue. Ordered techno circuit and it wasn’t the exact fit but I made it work and now it runs but sounds very loud and shaky and the Rpms rise really high and fast when I open throttle. It’s like it’s reving but it’s not catching and giving power it just revs really loud and crawls. If I barely turn throttle it catches and starts going then as I proceed with throttle rpms rise fast and gets loud but no movement/power or tires kinda catching. I have videos and pictures to help along the way. Please help me.
