[WPTA] SU Carbs

[Nick Gaten]

I have SU’s on my ‘59 Morgan, never had a problem but am trying a Weber 40 DCOE on a Midget I am restoring.

I’m wiring it from scratch with a Painless kit so the chances of it running are not good so it might as well look the part.

> * MG carburetors are infinitely adjustable. That is they can be set anywhere from “not quite right” to “totally wrong”.
> * Despite the above, a weekend working on the MG carburetors is preferable to fixing the oil leak.
