Nice meeting you at the event, Glad you could make it here. Need to get a compression check then then go from there! You can do this with a piston engine tester if a rotary tester is not available.

Have a fully charged battery!
1. Remove lower sparkplug and wire from front rotor.
2. Remove EGI fuse from underhood fusebox to prevent fuel and spark while testing.
3. Have an assistant crank the car over for you, while you listen under the hood at the compression pulses coming from this plug hole. Recommended to put your hand/finger right in front of the hole to feel the pulses of air.
4. There should be one strong pulse/whoosh of air per full rotation of the crank pulley. Use the timing marks on it as a reference. There should be 3 even pulses in succession, without skips or gallops.
5. If one or more pulses are weaker or non existant, this usually indicates at least one blown apex seal and severe internal damage. A full rebuild will be required, and no further troubleshooting will help.
6. If this chamber passes the compression test, replace this plug and repeat for the rear.
7. With both lower plugs out at one time, you can listen/feel for compression on both rotors at once. This should be a rhythmic ch-ch-ch-ch-ch-ch sound, like an old steam engine train, alternating front to back, once per rotor per rotation. Any skips or galloping indicate loss of compression.

Useing 2 people is allway helpfull.
To use the compression meter: remove only the lower plugs, remove egi fuse, keep the pedal to the floor and insert your tester into on of the leading holes. Hold the valve of the tester completly open. You should see 3 in succession, even bounces in the 30-35psi range.



Good Luck!
