This is leading to HTP papers being refused. Mainly affects cars with smaller Coventry Climax engines from the late 50s early 60s......
Of course Mike I have no idea of what I am talking about, but do own some fairly old books. The 250F Maser used 42DCOA3 Webers in 1954, while Ferrari used 50 and 58 DCOA3 models.

Probably no help at all. but I do like to show-off
