water only. Distilled or deionized water is
recommended, especially in areas where water
contains a high mineral content. Propylene glycol
based antifreeze is not recommended.
2. Fill cooling system, through radiator, with coolant
mix. Allow coolant to drain into lower areas. Fill
over fl ow reservoir midway between FULL and ADD
marks, then install radiator and reservoir caps.
Reconnect Spark Plug Leads and Battery
Connect leads to spark plugs. Reconnect positive
(+) battery lead fi rst, and negative (-) lead last when
connecting battery.
Preparing Engine for Operation
It is recommended engine be appropriately secured and
operated on a test stand or bench, prior to installation in

clamps are properly secured.
2. Make sure oil drain plugs, Oil Sentry™ pressure
switch, and a new oil fi lter are installed.

Testing Engine and Setting Speed
A
A Idle Speed Adjustment Cable
It is recommended engine be operated on a test stand or
bench, prior to installation in piece of equipment.
1. Set up engine on a test stand. Install an oil pressure
gauge. Start engine and check to be certain that oil
pressure (20 psi or more) is present. Run engine at
idle for 2-3 minutes, then 5-6 minutes more between
idle and midrange.
2. Check all cooling system components and joint
connections for leaks.
3. Using idle speed adjustment cable (on throttle body/
intake manifold), set idle speed 100 RPM below
speci fi ed idle speed setting.
4. Make sure maximum engine speed does not exceed
3750 RPM (no load). Adjust throttle and high speed
stop as necessary. Refer to Fuel System.
5. Place throttle control into idle or slow position and
check low idle speed (RPM). Refer to Fuel System if
adjustment is required.
6. Stop engine.
7. Recheck oil and coolant levels. Oil level should be at
F mark on dipstick, and coolant level in reservoir
should be midway between ADD and FULL marks.
Add additional amounts as required.
