I've tried it in the  workshop here - fit of all parts is good and it turns over smoothly, but I think  it needs a heavier flywheel to balance out the high compression it exhibits. The  engine is water cooled, complete with pump and radiator - in the original  application, the hot water was simply pumped overboard.  \u003c\/p\u003e    \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54020128702805,"sku":"2985","price":195.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/stationroadsteam.com\/products\/stirling-silver-ii-hot-air-engine-stock-code-2985","provider":"Station Road Steam","version":"1.0","type":"link"}
