Davo,

Sorry for the delay, we had problems in mid-December with the workload because staff were off ill or on holiday, and then we were closed from 21st December until today.

The engine wasn't built here - it went out as a kit.

It wouldn't start at first, and although we've now got it to start the start is still too slow. It runs OK once it gets going, so it's now undergoing a series of tests to find the source of the problem. I'll get back to you as soon as I can.
