    Positive piston stop

    With the addition of a locking nut under the slotted head of the screw, and a degree wheel, I was able to set up the timing on a '67 Triumph Bonneville that had no other marks or locators for TDC. Fits 14mm plug hole (13/16" hex flats)

    It's acceptable

    It's OK. However insert is a little bit loose in the threads, but stays in place. The center bolt end is finished with the threads, I prefer a rounded tip, which I grinded into it. In the end it worked, so I'm satisfied.

    Did not work on a Chevy SBC

    I found this tool to be useless on a Chevy 350 build. With it installed in number one cylinder and using a 16" ratchet I rotated the engine a full revolution and felt nothing. When I removed the stop tool, I found it to be bent but I never even felt any resistance. I then inserted an 18" section of 5/16 fuel hose into the cylinder rotated it until the piston stopped marked the location then rotated it in the opposite direction until it stopped again marking the location then removed the hose and brought it around till the pointer was exactly in the center of both marks and had perfect top dead center all with a piece of used hose that cost nothing, wish I had thought of that before I wasted my money.

    easy to use

    Just make sure you screw the stop in far enough. Great to use on an old engine when you aren't sure if the mark on the balancer is correct, or it's worn off entirely.

    Great product, great price

    Great product but unfortunately it doesn't work for my truck. Too small.
