Not to change the topic but Gregor, I'm not too familiar with rover engines that use spark plugs anymore--What exhaust setup is shown in your...um...garage photo?

Gregor does not have a LR engine in that 109- he has a 292 Chrvrolet I6 with some pretty cool Leo Santucci type goodies on it.

Sure looks like an early 1904 - they were used in Fords, Chevy/GMC trucks and IHC - as TerriAnn points out - From the early 50's to the late 60's. Unlike the Rochester B, I believe it only came in one venturi size, with only small variation amongst the mfgs - which helps simplifies things.

The reason you don’t see them recommended as much as B's is supposedly the linkage is much more difficult to convert. Doesnt look any worse than converting a Zenith for a B. Sure the Solex is drop in, but the Zenith linkage doesn’t take much. Could you post a better pic of the linkage?

Funny, drop by a Stovebolt board and they hate the B - commonly complain they warp and leak.

As far as the 1904's propensity for economy - Ive seen Rover claims all over the board - as with Webers.
