This product works well where the phillips screw driver can't get a grip on a rounded out screwhead. Works like a charm. Just a dab on the tip of the screwdriver.

This is the right stuff for lapping. Smooth and simple and easy. Just take your time and with ease you’ll have your valves lapped in no time.

I used this to lap intake and exhaust valves on a kawasaki mower engine. The seats were okay, but lots of black soot all over the valves. The first thing I did was cleaned the cylinder head completely with a brass wire wheel and some solvent. I found that diesel fuel works pretty good to loosen up all that black soot before using the wire wheel. Once it was all cleaned up, I removed each valves and MARKED THEM...(this is important as the intake and exhaust valves need to go back to their original position...don't switch them up...it's just a good practice...sometimes the intake aluminum and the the exhaust is steel. And sometimes they can be slightly different dimensions. So mark them when you remove them so you know where they go back in. I used a simple manual "spinner" lapping tool with the suction cup. You only need to use a little lapping compound. Don't go crazy trying to press hard while you rotate and grind the valve to the seat. Even slight pressure is best. After several rotations, use a rag and look at both the valve and the seat to see how much work you have removed. You really only need to remove a very small amount of metal. When the valve and seats look like new metal bright and shiny in a perfect circle of lapping, you are done. Now, this is the MOST important part. Remove ALL lapping compound..clean everything. especially the valve guides. You don not want this abrasive lapping compound left in the cylinder head. I used simple water and liquid soap...and then I use compressed air dry it ..and the do another soap and water wash to remove any trace amounts of lappng compound. I also use a small amount of motor oil to lube the valves before dropping it back into the valve guides.

easy to use
