Piston Timing Top Dead Center TDC Tool for 14mm Spark Plug Hole

Great tool

Can use for cylinder head (spark plug hole) or dropping it behind the fill hole behind the cylinder head it will drop into place

Good purchase

A little tricky to use at first, but once you get the hang of how it works it’s an extremely useful tool.

Piston Timing TDC tool

Nice sturdy tool, I received a gift card for Christmas. I was disappointed some products were sold out ; however this and two others were on hand. They arrive promptly and will make tune ups go more smoothly
