Product Information
Description:
It is a genuine OEM sourced replacement spark plug which is used with Honda engines commonly installed on lawn and garden equipment. A spark plug is used to deliver electric current from an ignition system to an internal combustion engine. Over time spark plugs tend to wear out, become dirty or fouled eventually requiring a replacement to maintain peak performance. You should gap your spark plug according to the owners manual of the outdoor product you have. This high-quality component is sold individually, please note you would need a spark plug wrench or a socket wrench to install/remove a spark plug.

Compression relief wasn’t working.
1. Removed engine from pressure washer.
2. Removed six bolts to remove side cover to access camshafts.
3. Discovered plastic pieces and wire insulation jamming up the compression relief mechanism on the camshaft. Plastic pieces and wire insulation came from the low oil pressure switch, somehow the wire to the pressure switch got got on the crankshaft tearing the insulation off and breaking the plastic molding around the fitting that passes through the block.
4. Had to order low oil pressure switch.
5. Removed the two screws holding the switch and the 10mm nut on the outside of the block, where the fitting passes through the block.
6. Reinstalled the pressure switch.
7. Cleaned out the debris in the compression relief mechanism and insured it was working freely.
8. Removed the valve cover and pulled out the pushrods to help reinstall the camshaft.
9. Lined up the timing marks on the camshaft and the crankshaft and slide the camshaft into position.
10. Cleaned off the old case gasket, installed the new one, and reinstalled the case cover. Tightened the six bolts.
11. Removed the four 10mm bolts on the valve cover and removed it.
12. Loosened the nuts on the rocker arms and reinstalled the pushrods.
13. With the piston at top dead center, adjusted the gap on the intake valve to .006 and then adjusted the exhaust valve gap to .008.
14. Cleaned off the old valve cover gasket and using the new gasket, reinstalled the valve cover, tightening the four 10mm bolts.
15. Removed the spark plug, checked the gap on the new plug and reinstalled the plug.
16. Removed the 10mm bolt on bottom of carburetor bowel
17. Cleaned out the carburetor bowel, installed new baskets on the bowel and the 10mm bolt and put the carburetor bowel back on.
18. Removed the wing nuts holding on the air cleaner cover and the air filter.
19. Removed the three 10mm bolts holding on the plastic hosing over the carburetor.
20. Removed the two Phillips screws holding on the metal cover to the top of the gas shutoff.
21. Removed the cover, spring washer and the shutoff lever, to access the shutoff valve rubber gasket.
22. Installed new shutoff rubber gasket.
23. Reinstalled the shutoff lever spring washer, cover and two Phillips screws.
24. Verified the shutoff valve was working and no gas was leaking out of the bottom of the
carburetor bowel.
25. Replaced the plastic housing cover and reinstalled the three 10mm bolts.
26. Installed the air filter and cover, held in place with two wing nuts.
27. Filled the crankcase with 0.625 quart of 30w oil.
28. Checked for oil leaks.
29. With the gas and choke in the on position, pulled the rope starter and started the engine.
30. Much easier pulling the starter rope, with the compression relief valve working. Motor didn’t kick back and rip the stater rope handle out of my hand.
31. With the engine running, shut off the gas valve and let the engine run out of gas to verify gas shutoff valve was working correctly.
32. Reinstalled the engine on the pressure washer.
33. Connected the water hose to pressure washer and started the engine.
34. Pressure washed the motor in my truck.
35. Pressure washer worked great and the motor didn’t rip the starter handle out of my hand when starting.
36. Successful repair!
