Hey Grumpy, thanks for your reply.
I see what you're saying regarding taper needles and main jets. However,the needle on the machine I bought for some reason had gouges in it and was slightly bent, this is why I replaced it. Everything seems to be running pretty sweet at the moment, but I've still got the old bits just in case. By the way, I never realised that the needle and jet don't actually touch each other, that's very useful information
Cheers,
Craig
p.s. My user name 'Mark_x11' refers to a Villiers MK 12/2. The X11 being Roman Numerals. This was the first engine type I started messing around with. I thought it was a good name at the time but now......
