A PAIR OF OLIVER TIGER MK3 ENGINES TO REDEEM.

These two engine were sent in by my good friend Callum Agnew with the request to "please make them new again". No problem mate.

Here they are as we received them.

Not looking too bad on the outside, lets pull them down and see what's on the inside.

Well here they are all dismantled and ready for cleaning.

Here's the first case all cleaned and ready to start reassembling.

Original crankshaft cleaned and refitted with new bearings front and back. New Back plate also made and ready to fit. Prop driver cleaned up and going back on.

New prop washer made and fitted and the original prop nut cleaned and reused.

Here's the cylinder liner and piston assembly for this engine which is a standard engine.

Piston and contra piston blanks all ready for final machining and fitting to the restored cylinder liner.

And all finished and fitted up ready for reassembly to the engine.

Now we'll do the second engine so they are both at the same stage.

Here is the cleaned up crankcase for the second engine which appears to have been modified for racing application. We will therefore restore this engine to full race spec.

And a new back plate made and test fitted.

Here's the cylinder liner and replacement piston etc for this engine.

Piston and contra all finished and fitted up ready for reassembly.

Next up is the con rods for both engines.

And here's the new rods for both engines all finished.

Now we'll assemble the original engine and move on to making the new crankshaft for the race engine.

Here's the first stage of the replacement crankshaft.

Next step is to machine in the big end and porting.

And all the porting is now done.

Now to reassemble the bottom end of the race engine.

Here he is with the new crankshaft all fitted up on new bearings.

Here's the new lightened piston and rod assembly with the restored liner and new contra.

Cylinder head cleaned and refitted

Now all that's required is the N.V.A to be cleaned up and refitted and we'll be ready to add some fuel to these bad boys.

Here are both the engines all ready to turn some fuel into noise and smoke.

Now where's that fuel bottle gone?

Here's the first pop test run for the standard version mk3.

Here's the hot restart test run of the standard engine.

Now we'll get the race engine ready to run.
