#703 ECONOMY COMPRESSION TESTER
Compression is the FIRST test
you should perform on any engine!
Use this one when you have
no clearance problems. For professional compression service I recommend #
- Tester screws into 14 mm spark plug hole on outboard
- Use to check for low compression.
- Measures up to 200 psi or 14 kgs.
- Will help diagnose engine problems such as: burnt valves,
scored cylinders, leaking head gaskets, tight tappets,
broken valve springs, broken rings, damaged pistons.
plus $8.75 postage and handling.
