I wanted a leak-down tester and they cost over 200 dollars, so I decided to make my own. I used a solid acetyl copolymer rod and drilled it out and drilled and tapped the holes for the brass fittings. I bought the gauge from Amazon for 20 dollars. Came out fairly nice.
The Shop
The compression tester, or compression leak down tester, thread in the spark plug hole.

I've done leak downs on 2-strokes through the spark plug hole, the intake, and the exhaust. Just need to find the correct plugs. The object in all three have always been the same, check for leaks on crank seals, center cases, base gaskets, and head gaskets.
