Gentles,

A few days ago spoted a Petter A1 at FaceMarket.

The add got a trolley with a 3" pump, and the A1. After discution with seller and show him my only interessest in the A1, he handup acepting my offer, and agree to pull the engine from the trolley.

And now put hands on the job. Let see if this one doesnt let me down.

Cheers.

Gentles,

Couldn't resist. The A1 came down half stripped!

While striping it noticed it is a oversize at max. .040".

It doesn't look too bad, but the magneto will decide his destination.

For now just a few pics to the show.

A few more pics!

And meanwhile, I asked help to the Internal Fire Museum of Power to date this engine (you guys dont forget to make a donation in order to preserve the volunteer work of the process of getting data).

This engine was sold to power a genset. It is dated from 5JUN1953.

It's in the wedge and bang phase!  ;D ;D

It got a taper lock sheave class 2DZ112, with 1 1/2" center.

Gentles,

The A1 is going down.

Mag was clean, and its sparks! Good sign.

Fuel tank was changed to a stainless tub, and they save petrol filler neck, and 1/4 tap threads.

For now the option will be to make the fuel tank shiny.

Got to stop the wedge way to pull jibkey, otherwise it will broke. And so I made a custom puller.

A few pics to the show.

Cheers

Cam shaft it out! You can notice the cam has a lobe to run the oil pump, but this model is splash lub.

Thrust plates are bronze and crank pinion got it pretty worn, and was mounted backwards with shims.

The custom puller was made an the fly. It ended to be grateful.

After gibkey out, time to pull cylinder, piston and conrod. Anyone can say were gone the eyes of the circlip?

As far as I can see big end shells are in good condition and at standard spec.
