Thank you for the info on either, as i can,t buy any all should be ok. It,s easy to buy diesel fuel from at least two model shops and they will send it to you by courier, and thats to anywhere on the UK mainland, but, i live on a small island and the regulations don,t allow it to be transported by air or sea so no one will try and send it, as soon as my address shows up on the order red symbols come up , there,s a problem contact us, when or if i do contact the supplier, shop, they tell me there,s no way it can be sent, also unless people lie it can,t come in luggage. So making my own is the way to go for me. I know John Deerer is the best starter spray but getting that is not easy, probably sometimes on ebay. When i get all i want , iv,e been waiting for castor for two weeks, i will get a test stand made use the only igniter spray i can get locally give it a go and let you all know.
