Thanks Steph.
I'm certainly happy with where I am so far, but not, now, with the back head! I reckon it's helpful to have this in the public domain as there may be more assistance out there which will help me to determine t'other from which.
My reply is:
Thanks for this help, Steph.
The problem for me is that I don't know what is what! I sort of made it up as I went along. I don't have a good photo of the back head except for an LBSR one, and those I do have are a bit gloomy. I have a drawing of a B4 back head, is it? The one for the Atlantic isn't a lot of help. I think what I may do is wait until I see you to complete this, but I'm glad I put the photo up so I can be put right! Roger Scanlon has sent me a similar PM.
As ever help will be gratefully received. Initially, perhaps, so that I can identify the injectors and also the backhead clacks. Once I know what these are I can at least start to put that aspect right! I'll then drain the rest of the knowledge from the assembled throng.
Would have been helpful to have a drawing of a typical backhead included in the instructions, though, would it not?
