This is an exhaust valve rocker arm used for small engines and equipment like pressure washers. Rocker arms transmit motion from a camshaft to valves, controlling valve timing and duration. If your engine struggles to start, misfires, or will not start, inspect the rocker arm(s) for excess play, wear, or bending due to high temperatures. To replace it, disconnect the spark plug and/or starting coil, remove the valve cover, and locate the rocker arm(s). Rotate the camshaft until pistons are up and rocker arms are loose. Slide out the pin, remove the old rocker arm, and install the new one with its pin. Tighten the adjustment screw to the manufacturer specifications, reinstall the spark plug, replace valve cover sealant, and reattach the cover.

Honda GCV 160 Pressure Washer Wouldn't Start and was difficut to pull.

When I start my pull start motor I try to start them at Top Dead Center knowing this and experiencing the kick back almost immediately after pulling the cord and feeling the high level of tension getting there I immediately suspected a stuck exhaust valve.
I took the 4 valve cover bolts off and carefully pulled the glued on valve cover off to see that the rocker arm for the exhaust valve had been split. When the rocker arm was putting force on the valve and the valve didn't move the rocker arm broke. Fortunately the exhaust valve wasn't so stuck that 2 taps with a dead blow hammer freed it right up. Replaced the rocker arm and set the valve clearance to specifications and verified the intake valve clearance as well (clearances was set to 0.15mm intake and 0.20mm exhaust).
A few things that I took note of since this was the first time I have worked on the this motor. Most of the motor does not use gaskets it calls for Honda Bond 4. I Permatex Ultra Grey RTV. You could also use Yamabond 4, but the Permatex is cheaper and more readily available.
This motor does not have a removable cylinder head. If you have a ton of hours on your motor maybe 100, 200, maybe 500. You may as well tear the motor completely down anyways and replace the timing belt clean the cylinder head (Which you have to do by going in through the bottom of the cylinder, and inspecting the parts of the bottom end). I didn't even consider doing all that because my motor had less than 50 hours on it.
My Lessons learned from this is that in addition to what the manual says to do for long term storage I will also be taking off the muffler and carb to have access to the intake and exhaust ports. While cycling the motor with the starter rope I will spray some PB Blaster on the valve stems as additional lubricant to the motor oil that already got poured into the cylinder, and then cycling the starter rope to store the piston at TDC(top dead center) to trap out any moisture that could possible freeze up the valves.
I know this was lengthy, but if you took the time to read all that I wrote I hope that it'll help you in the future with your equipment repairs.
Thanks,
James

After reassembly, did not have any compression, found adjustment out on the rocker arms, was keeping exhaust valve open a little, not allowing compression to build up. Adjusted, then after two or three pulls, engine started.
With the timing belt, it is important to make sure that is reassembled correctly to have valves timed properly. Found a video on youtube that explained how to do that.
