Engine Compression
Check compression with engine warm, all spark plugs removed and throttle wide open. Crank engine through at least 6 compression strokes per cylinder to determine engine compression.
CAUTION:
On models with electronic ignition, connect coil high tension wire to ground before cranking engine.
