110 cc Loncin wiring help
 

Ive gotta 110cc Loncin engine that was wired up and running previously. i took the bike apart and repainted and changed some things to the frame. It was wired into a switch on the handlebars but had no spark. The harness was a mess so i took it off. My question is how or can i wire it to a push button start instead of a key start. Ive read some other postings about wiring diagrams but none witgout a key start.
