Thanks for the good advice.
I don't want to pull it apart until springtime, i live on a farm with a 1/2 mile tarmac drive so i can run it regulary to keep everything working.
Can't turn off fuel at tap, it has no off position.
As i use my @ through the winter, i have no wish to tax the Trophy as well.
I'll have a look at the other makes mentioned, thanks guys
The reason i looked into this, i have a customer with a collection of classic cars, including a couple of rare Aston Martins, and he swears by it, stops all the usual problems.
