New to motorbikes from CA

My name is Mike, from Los Angeles. I've been into classic Fords all my life(mainly 60's). I've recently gotten into prewar American bikes & already have quite a number in my collection. I picked up a cheap early 60's Murray frame/forks & it's been lying around for a while. Then I found a cheap Bike Bug motor on CL. Decided to bolt the two up, but have been having issues keeping it running. Hope to learn some info here & also make some friends. Thanks!
