Inlet Manifold to Fit SU Carburettor to a Ruby

Thank you, but I think that I have one sorted: just waiting to confirm.

Ian.
I am hoping that the carburettor will be all right for the engine. The engine has a high compression head, a modified camshaft, shortened cam followers, smoothed ports and the John Barlow inlet manifold. The head and block have been very lightly skimmed to ensure that they are flat, which I imagine has increased the compression ratio a smidgen as well.

The carburettor cost me £9:00 and I have fully refurbished it, including a new butterfly valve spindle: oddly, the old spindle had worn badly, yet the bushes were fine. The new spindle went in snugly.

I hope to run it on a dynamometer, so I should be able to see how it goes when I have it fully assembled it. If the carburettor does prove to be too large, I shall change it.

Regards,

James.
