SBE8 Valve adjustment

Tim:I have the SVE-SBE service manual and they say the intake/exhaust valve rocker arm clearance should be 0.2 mm. The instructions are as follows: 1. Remvoe rocker arm cover.2. Align T.D.C mark of flywheel with datum mark on crankcase.(piston should be on compression stroke)3. Loosen locknut of adjustment screw. Measure valve clearance with thickness gauge and adjust to 0.2 mm.4 Tighten locknut firmly.Hope this help and solves your problem.good luckBill
