You will find everything that makes the Wilesco engine run properly. It could be just a washer for a safety valve, regulator or something as big as a new boiler for the Wilesco Old Smokey engine.
Our best sellers are the whistles and safety valves with regulators following close behind. Wilesco engines are usually reliable except the plastic whistle and regulator arms can break or wear a bit allowing steam to escape. In this case a new part is required.
One particular problem sometimes arises when the water level sight glass assembly comes away from the boiler. Choices then become a bit expensive unless you are quite handy at soldering with a butane torch. But we can tell you what to do.
If you are not sure what you need, why not email your question for a quick answer to help you get that project completed. We are always happy to advise.
