e. Engine Idle Setting
Set idle adjustment to obtain a smooth idle at
650 rpm.
f. Ignition Timing
Disconnect distributor vacuum line, set ignition
at 8 degrees BTDC, and reset engine idle back
to 650 rpm.
g. Valve Timing Checking
Turn the crankshaft until Number One intake
valve is closed and Number One piston is on
Top dead center (TDC).
Install a dial indicator so that the pointer
contacts the valve spring retainer as nearly at
a right angle as possible. Since the C-300B in-
corporates mechanical tappets, it is not neces-
sary to allow time for the tappet to bleed down.
Adjust the valve rocker screw to afford zero
clearance. Then set the dial indicator to zero
and turn the crankshaft clockwise (normal
running direction) until the dial indicator
shows that the valve has lifted .081 inch.
The timing marks on the vibration damper
should read from 5 degrees BTC to 7 degrees
ATC.
If the reading is not within the specified
limits,
check the gear index marks and inspect
the timing chain for wear.
Before making this check, determine the ac-
curacy of the TDC mark on the damper by
bringing the number one piston to TDC with
an indicator placed in the spark plug hole.
After the valve timing has been checked, reset
the valve lash to the specified operating limits.
