i have been thinking while working on the wall with my head . a new way to check piston to valve clearance.up for consideration that will be marketed and sold by me it will come in a very nice box that has the mccarthy performance logo in fine irish green on the box . in the box it will look just like a tootsie roll to check piston to valve clearance . it will look just like a tootsie roll and when done take it off the piston and you can eat it
