SD on the bay

[Horsley-Anarak]

Looks like it is an honest motor

Could be a little steep at £180 starting price.

Not sure on the tiller grip, I would think it would have been rubber.

Looks very much like my one, even has the short Champion cap with the extension piece.

Be interesting to know the number, also can't see a copper top magneto, could be clever photo angle.

If the seller is lurking "fess up", If you are selling that motor on the internet, you are looking at this forum!

Looks like a mk2 magneto. Domed nut doesn't look brass. Brass bodied Amal is a nice bonus. What is the WD marking he speaks of?

Another silver block.

When will they ever learn? the fuel pipe is that long, as the float chamber goes the other side of the throttle slide body.

Are WD markings different to Chief Inspector of Engineer & Signal Stores stamp? And where does this info come from " and has the WD markings for inshore boats work Probably Navy/Army landing craft."

I am not sure that is correct, my one had a loop running near the exhaust, as does one of Jan's.

The pipe on mine showed no distress and was not misshapen or distorted at all.

I will not be bending it to fit the other side of the carb body, as it fits well there.

What do you say Jan?

I have two with the pipe tucked back to prevent damage and both have bowl at rear. Pipe close to exhaust tho.

I agree with Charles.

Early 102 advertisement pictures shown the float chamber on the operators side of the carb body.

The float chamber will touch the C-clamp during steering so many owners changed the float chamber position.

I changed the float chamber position to the correct side on all my early 102's and re-shaped the fuel piping.

Btw a very nice SD.

Not convinced, there are too many the same with exactly the same bend in the pipe.

I know the advert you mean Jan.

Shorter pipe and different shape.

The only benefit I can think of having the float chamber nearest the boat, would be when the motor is tilted out of the water,
there would be less chance of petrol from the float chamber ending up in the cylinder.

As these engines were not used on the conventional transom brackets, then having the float bowl near the cylinder could be how they left the factory.

I think the pipe near the exhaust must have been done for a reason, low quality low octane fuel or oil rich Benzole mixture may have worked better with preheat.

Who has untouched boxed SDs, or ones with the float chamber "on the wrong side"?

Perhaps one day the wartime seagull MOD instruction book will show up, and answer my question

Until that time I will leave mine as is, perhaps in original condition.

Yes that's a straight pipe
Agree with H.A
Would give good money for a carb like that!

[Jan]

I think your right H-A,

Just checked mine SD' s and they have all the chambers on the petrol tab side.

A picture from the SD working instructions showed also petrol tab position of float chamber.



Only my early 1947 102 has the float chamber on the crankcase side.

Pre-heated fuel sounds plausible.

Instruction manual, provisional, 1942

On this one the pipe is running close to the exhaust, and the float chamber position is quite clear. Is that the usual petrol cock?

I Love all of this Guys!

Watching this post aye!
