B. Turn fuel valve ON to desired fuel tank.
C. Set mixture control - FULL RICH.
D. Open throttle control approximately 1 inch.
E. Master Switch - ON
F. Push boost pump switch for 3- 5 seconds until
positive indication of fuel flow is obtained.
G. Clear propeller area.
H. Start engine. Check oil pressure. If no oil pres-
sure (min. 10 PSI) is indicated within 30 seconds, shut-
down engine and troubleshoot oil system. Refer to CMI
maintenance publications for procedures.
I. Set throttle for idle, 600/700 RPM, for one min-
ute, then advance throttle slowly to 900/1000 RPM for
engine warm- up.
3. Ground run and warm- up.
Always head aircraft into wind during warm- up. Always
select high RPM blade- angle setting when ground run-
ning engine. Never idle for extended periods at low
RPM (low RPM will foul spark plugs). Operate with mix-
ture control at FULL RICH (leaning is permissible de-
pending on ground elevation); maintain RPM in
900/1000 RPM range during warm- up and ground run.
A. Warm- up engine until temperature indications
are normal. Monitor cylinder head and oil temperature
instruments for over- temperature.
B. Check magnetos at 1700 RPM with propeller at
high RPM blade angle. Switch ignition- starter switch
from BOTH to RIGHT to check magneto drop. Switch
back to BOTH until RPM returns to normal. Switch from
BOTH to LEFT and check magneto drop. Return switch
to BOTH. Magneto drop should not exceed 150 RPM
(normal is 75 RPM drop) on either magneto (drop
should be within 50 RPM of each other). A smooth drop
off past normal is usually a sign of too lean or too rich
mixture. If no drop in RPM, check for open or broken P-
leads.
4. Cold Starts:
Same procedures as Normal Starts, except more boost
may be necessary. After engine starts, it may be neces-
sary to operate Boost pump intermittently to prevent
engine from stopping.
5. Flooded Engine Starts:
A. Mixture - Idle Cut- Off
B. Throttle - 1/2 Open
C. Ignition Switch - Turn and push to START
D. When engine starts, return Magneto/Start
Switch to BOTH. Retard throttle. Slowly advance mix-
ture to FULL RICH. Adjust as needed for elevation.
6. Hot Starts:
Same procedure as Normal Starts, except:
A. Mixture – IDLE CUT- OFF
B. Propeller - Full Forward (High RPM)
C. Throttle Control - Set to Closed
D. Boost Pump – HIGH for 5 seconds or LOW for
25 seconds then set to OFF
E. Engine Start - follow Normal procedures
7. Extreme Cold Weather Starts:
Refer to CMI Engine Operating Manual OI-18 Sec-
tion 7.5.1 for extreme cold weather starting proce-
dures.
71-00-50 - ENGINE SET UP PROCEDURE
It is recommended that the TSIO- 550- G( ) engine
installed on the Mooney M20V aircraft be set up ac-
cording to the following instructions and in conjunction
with Continental Motors TSIO- 550- G( ) Maintenance
and Operator’s Manual and Continental Motors Over-
haul Manual, appropriate CMI Service Bulletins and
Continental Motors Service Information Directive
SID97- 3(G) or latest FAA approved revision.
-CAUTION-
Watch for rotating propeller during engine
adjustment.
71-00-51 - FUEL INJECTOR ADJUSTMENT
For operation in normal or low ambient temperature
conditions, adjust idle pressure, speed and mixture as
follows:
Check magnetos; if magneto drop is normal, proceed
with following adjustments.
FUEL SYSTEM OPERATIONAL CHECK
PORTA-TEST UNIT SETUP
1. INSTALL TEST GAUGES/FITTINGS
A. Loosen the unmetered fuel supply hose from ei-
ther the fuel pump outlet fitting or the fuel control inlet
fitting, depending on access to connections. (Fig.
71- 3).
B. Connect one MS51523-B4 swivel tee to the fuel
connection loosened in Step A.
-NOTE-
Some installations may require a number of fit-
tings to adapt the metered and unmetered test
equipment to the fuel injection system.
C. Connect the unmetered fuel supply hose to the
straight end of the tee connector.
D. Connect the Porta-Test Unmetered Pressure
hose to the tee connector.
E. Remove the cap from the metered fuel port fit-
ting on the fuel manifold valve.
F. Disconnect an upper deck pressure fitting at the
throttle body or intake manifold. Install an MS51523-B4
swivel tee in-line with the upper deck pressure fittings.
G. Connect the Porta-Test Unit metered pressure
test hose to the metered pressure fuel port on the fuel
manifold valve fitting.
