gets fuel and spark but wont start

 

Maybe carb related but if it won't at least try to kick off with starting fluid,it might be that cursed Ducati ignition even though it has spark.They can still show spark,but the combo cdi/coil pack is what times it. To be sure you can tear the carb apart,may be needed anyway,install a good Shindy carb kit. https://www.ebay.com/itm/Shindy-Carb...JaAzZN&vxp=mtr If that still doesn't help you may be down to the ignition upgrade.
