After break-in oil, you need the timing light monitoring your timing the first ten minutes. Before first startup, pull plug number one and verify that DTC there matches your timing marks. A lot of engines are recommended at 8 degrees btc, but look yours up to see what it should be when running. If your timing is too far off, the valves will start touching the pistons and putting pressure back through the valve train that can also cause a virgin cam to wear out early before it has broke in and been seasoned by the zinc in the break-in oil.
