Are you running a minimum of 100 octane race gas or E-85? With 13 to 1 you are not going to be able to run common pump gas, or you will melt or break something in a hurry due to detonation.
If you can't figure out how to set the valve lash and basic timing, you are going to either have to watch how to do it on Youtube, get the help of a knowledgeable Technician or study the vast information on this site for a few weeks before you do know how to do it. Then you will need to tune and adjust your carburetor to get the jetting right. That means getting a wide band O2 sensor and gauge installed and then learn how to use that.
