Freshly Overhauled Engines from two of
Ontario's Finest Engine Overhaul Facilities

We have been working with A.T.C. (Orillia) and Leavens Aviation (Toronto), for some time now,
to allow us to supply you with freshly overhauled engines for installation in your homebuilt aircraft!
The following engines are currently, or soon to be, available (subject to presale of course).
Please contact us by e-mail at
oifa@irishfield.on.ca for more details in regards to these engines.

One - LYCOMING O-320-A2B - Narrow Deck - 150 HP

We have a complete engine in parts.... disassembled and inspected by A.T.C.
Cylinder assemblies have been bored and Nickle Chromed back to Std by ECI.
 The Valves have been installed with new guides and the pistons/rings have been fitted.
Fresh O/H camshaft, lifter bodies and plungers. Used mags and all associated
 hardware for assembly, drive gears, accessory case pivot shafts etc.
 Crankshaft has some pitting on the, currently Std, thrust bearing face that may
not come clean by turning underize. Wouldn't hesitate to use it in an airboat
and may come clean enough for your experimental as well.
 Open to serious offers on the SOLD SOLD SOLD we have into this engine, to move it.
