welcome mate if its a 199 should have the number 199 in the long number.have you checked the engine number to see if its the same? if theres no spark dont be to quick to think its the timming could be something simple like the plug cap may need cleaning or not connecting may be cut a small bit off the end off the coil wire. this happend to me once no spark so i cut a small bit off the wire and it sparked. failing that then check the wiring. may be a brake in the wiring or the kill switch if it as 1 has not be wired up correct. or it may not be earthed. all things you should check before timing and points hope this helps.
