Could you please tell how to adjust overhead valves on this engine??

1. Remove the tappet cover. (says OHV on it),
2. use the correct torx driver and wrench , and feeler gauge, I believe .005 on intake,
And .006 on exhaust. Adjust and secure the locknut when you have the
Correct fit with the feeler guages.
3. install a new tappet cover gasket, and install the 4 bolts.

NO GO 1/4" PAST TDC ON EACH CYLINDER TO SET THE VALVES.

And no I am not Yelling, I am just making it easier to read.
