This is a genuine Generac replacement part that has been sourced from the original manufacturer and is intended to be used with small engines for portable generators. The gasket is used to seal the connection between the valve cover and the cylinder head. This item is available as an individual replacement part.

The rears were too tight and the fronts too loose.Followed directions on finding TDC from internet forums and YouTube vids. The hardest part of this job is finding the \"sweet\" spot so that when you tighten the lock nut your adjustment is in spec. I was shooting for a .004 clearance so what I ended up doing was getting it to .003 and then when i snugged up the locknut I ended up at the .004 as this action increases the clearance slightly as the adjusting bolt will turn slightly as well. After this first time I am sure that I can cut my time in half next go around. Take your time, check and recheck gaps and only do this if you are confident in your wrenching skills. Fire it up, check for leaks around the valve covers and relax for another 400 hours or so.
