OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Engines Precision Eng. & Amplion - Stationary Engines

I picked this engine up from a friend of mine, it was locked solid and full of water. Australian made by Pecision Engineering in Sydney. It is of course a Briggs and Stratton clone engine, Amplion also manufactured a clone as well. I have recently acquired an Amplion and there are some minor differences in the build.

CyberJack supplied some material showing the genset which I believe mine was once a part of. I found army green paint on mine so maybe it's an ex army unit.










More to follow

Here is a manual for it which covers all of the clones and is free to download from Briggs and Stratton

:-) I have a block with a very good bore for a Briggs, interesting thing is that there is no markings on the Briggs block but Amplion put there name on the camshaft moulding. Precision left theirs unmarked as well

More progress, had to order a new conrod from the States and a fuel filter



Rings fitted and valves all done






Ring fitting information



I used the piston that came with the Amplion block as it was the better one



All went together nicely, cleaned up the points and checked for spark. Nothing !



Pic is upside down as Photobucket couldn't rotate it


Coil was buggered, went to my spares and found a good coil


Setting the air gap using a 0012" feeler strip






After giving the exhaust valve a grind to give the correct clearance the head is ready to fit

Progress so far

Hi Paul,

You started with an unknown engine, as you have brought both the
name 'Precision' and your engine back to life (almost).

I do feel this was a war contract machine.

Cheers

p.s. I love the Edison Albanite plug and your feeler gauge.

looking good Paul, love the old spark plug!

Finished it off today

Thanks for your help with this one Jack and also taking an interest in the post:-)

Thanks Kye, the plug was a nice find in another engine.

I now have an Amplion engine that was made to run a washing machine. It sits very low with the fuel tank mounted on the lower front of the cowl. Fitted with a suction type carb and a kick starter. It is another Briggs & Stratton clone engine. It must be a pretty rare little engine because I can't find any information on it at all.

Amplion engine

G'day Paul and Members

Thanks for sharing the videos and recording this engine.

That this engine was used on a washing machine is unusual in AUS.
In the USA they were extremely popular with rural America prior to
electrification. To find any petrol-powered washer here is not common.

In Amplion advertising here, the engine was a general purpose, but ads
refer to pumps, saws, milking, honey extractors, compressors, sprayers,
separators, grinders, generators, lawnmowers, but no ... washers.

I don't know why. It may be that rural Australia prior to WWII simply
did not have the wealth - that a working class nation could not do this...?
Amplion engines only became available post WWII when rural Australia was
becoming 'electrified'. Maybe the market never existed here.

I know that Briggs and Maytag made specific washer engines, but I cannot find
specific reference to this application in this country.

Any thoughts?

Hi Guys,

Pretty new to the forum and haven't posted previously.

I recently picked up an Amplion Generator set which appears complete but not working.

Also a Jonson Chore Horse Generator set which appears to have a shorted armature.

Looking for any info which may help on the generator and motor side

Once I work out how to upload a photo of them I will.

Thanks,
Dail
