Thanks Stu, Its a Case of asking the right questions Very Happy

No more engines now..Been warned, well got to wait until my son turns 1 Rolling Eyes dont know if that included pumps....

my T300 is on perminant loan to my uncle, who is also member on here Chyangwel. and my tank cooled WX11 is off on Sunday.

Got to find a centrifugal pump to create load on these strokers, I may know where there is one, and there is one on ebay, but that might go for silly money, I might sell my domestic pump as its not great for adding load, but my grandad bought it me, and as he has now past on got a bit attached to it, as you can see I have had it a few years!

Steve can you not reduce the pipes on the domestic pump to add pressure, that would help to load it up.

Here is some of its interesting features.

The PA stationary engine however was different. Designed to meet a Ministry requirement for a portable electrical generator for the Bofors anti-aircraft gun and its Kerrison Predictor, it was produced during the Second World War by both Scott and its former partners Jowett. It was air cooled, petroil lubricated and featured a loop scavenge design with two opposed main transfer ports supplemented by a third "boost" port opposite the exhaust. This arrangement was patented by Scott in 1939, but is often mistakenly believed to be of post-war origin as it was later widely adopted for motorcycle racing engines and power boats after its "reinvention" in the late 1950s by East German motorcycle manufacturer MZ.

And this is also Quite interesting

the induction cooling is fairly novel too, with almost the entire engine encased in a cowling. The casting around the cylinder has fins on the inside which mate with the cylinder fins creating a very rapid and efficient air flow between the two matching pieces. Air is drawn down from the top of the cylinder and expelled through the flywheel, instead of blown over. The exhaust system also deserves a mention and is designed for exceptional quietness. There is an expansion chamber immediately adjacent to the exhaust ports, from which two exhaust pipes run to the hollow chassis cross member, which is a second expansion chamber. This in turn communicates with two more hollow chassis members which act as silencers and also the bedplate for the unit, it is quite unusual for the engine to retain this exhaust system as it is normally butchered off to make them easier to move. so feel quite luck to have a complete one.

Cheers Steve

You found a good un Steve well done.
I have to say there's no getting away from it that the British built great engines lots of thought went into them loads of great ideas, yes some didn't work out but on the whole the British engine (have to add motorbike) builders were some of the best in the world. What a shame we lost them all Crying or Very sad except a handfull.

Atleast im not the only one that finds its design quite interesting! Its quite a ugly beast but I think thats why I like it Very Happy
Quite happy that we beat the Germans to the boost port design lol! just a shame that MZ get the credit!
Its also a shame the handful left are owned by jolly foreigners.

Well I have another Scott in my shed (not 100% if its a PA or PAB?) but here is the pics:













Few close ups of the exhaust system







I think its a Marmite engine with the looks, but its such a interesting engine, Phillips article in SEM are well worth a read.

no we know that you can be sharped tongued.....
it was that over the weekend at Kingsley, i was told by a feller that you had a problem with me....
who he was i don't know,ive never seen him before,but he did say that you were feed up with my attitude,so rather than let it stew i want to see what the problem was,so we can sort it out the proper way.unlike some who shall remain nameless just go around stirring the sh-- and haven't the balls to say it to the persons face...i cant stand spindles people like that..if anyone has a problem with someone then tell them to there face....that's what i call the proper way...
