I notice that you've put a nice polish on the inlet stubs.
I'm very likely to do the same someday.
Now, I realise that the difference it makes is miniscule but, just for interest's sake, what are your thoughts on whether the shiny surface is better for the carburation, or worse.
My thoughts are that it may well be better, as the polished surface would absorb less engine heat than the original, slightly matt finish ( thus keeping the mixture cooler).
If the shine makes it worse though, even by a tiny amount, then I probably wouldn't bother.
Shiny is nice, but not at the expense of efficiency. That would be sacrilege really.
