Check compression and spark. Spark should jump a gap of at least 1/4″ in an open air tester. If compression and spark are good, could be timing is off. You may need to do a link and sync. Make sure carb butterfly just starts to open when the pointer to the left of the follower roller hits the mark on the cam. If not, loosen the cam and adjust to make it so.
