October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Testing Compression
- Disconnect the BAT terminal from the HEI distributor or ignition module. Check compression with engine at normal operating temperature, all spark plugs removed and throttle valve wide open.
- Insert compression gauge and crank each cylinder through 4 or 5 compression strokes. The lowest reading should not be less than 100 psi (7.0 kg/cm2
).
