Roy,

I am very pleased you received it in the end. It is an added bonus that the interesting postal system in SA didn't in the end gouge you for more cash. You would never have known where it was at all if it was not a tracked parcel, and doubtless never received it.

All the best

Opened, X rayed I suppose I can at least be certain the parcel you sent was safe !

Stripped and cleaned and reassembled, I will strip it again and flush it out with clean petrol, then do a test run of this rebuilt 102 series bitsa engiine.

That's a sought after early Amal used on the World War 2 motors. Note the Amal script high on the float bowl. Highly desirable. Good find.

Those wartime carbs seem to have some sort of maybe zinc coating, rather than the later painted ones. I'm looking for one for my HSD project if anybody has a spare :P

I have one, would like to keep the shroud, but carb is available, if I can find it.

Sorry pictures are not the best.

Thanks for telling me, I will be keeping this Amal 2 jet I think?


I was very complete, seized solid but as my picture shows was all there.

Would painting it be acceptable, then again will the paint accept our modern petrol?

The first attempts to start the 102 series motor saw a petrol leak at the joint where the two flat washers and banjo bolt meet.

I did file the flat metal surfaces, also tried other washers, the leak continued so for today I used some black O rings, they are not made from Viton so I can expect them to fail.

Some twenty four hours later and still no leaks from the black O rings, I think if I replace them with Viton O rings or even Viton washers I will sort out the issue with the flat faces that the banjo bolt has to clamp to.

I needed some more 10:1 two stroke mix to lift the fuel up in the carburetor bowl, once that was done I had a runner.

Note the hand throttle for now.

The exhaust burns clean enough, the motor sounds really good and I have a runner.

I now need the parts which are in the post, which includes a water pump housing.

I also need a water pump impellor, does any one have the dimensions and I can make one myself.

My thanks to Fleeting contact for supplying the Amal 2 jet carburetor.

I have read that two sizes of water pump impellor exist, am I correct in thinking that one suits motors such as the 102 series (others also) and the smaller impellor the Forty series?

If so why do I have two water pump houses with different diameters, both are suitable for the larger gear boxes?

One is 2" and the other 2 / 1/8" inch.

Am I missing something here please?

It could be this thread ends here, as I have restored the seized powerhead to a working condition.

Engine number being WHCH 144R8

As I am still missing a suitable gear box and water pump assembly, I will have to wait for one to find its way here someday?

I am told that the lower fitting that I have (damged) to fit to the power and exhaust tubes is correct for the 102 series motor.

Working on that information I now have what I have, damaged or not, it can be alloy welded and I can file and grind the shapes required , the thread in the good tang is good.

The waterpump diameter is 2 - 1/8" in diameter.
