Socket set, 1/8 inch allen wrench to use on the adjusters.
Replaced rocker arm adjusters,and adjusted them. Only problem I had was I thought i needed a torx wrench for the adjusters but come to find out it takes an 1/8" allen wrench. Be careful ordering these rocker arm adjusters it seems they made metric & sae adjusters for this model, mine was sae.

Tripped head off, inspected all parts, cleaned carburetor bowl while I had it off the engine.
I checked to make sure head and cylinder surface wasn't warped, de-carboned piston top and head. Re-assembled.
This type of repair is pretty straight forward.
If your new to this, keep nuts and bolts organized, and it goes easy!!
