Anyone got any idea of the jetting and chokes (weber 40s)I should start off with for a 2.4 T engine, converted with new pistons at 9.5:1 CR, and E cams. Also what ignition timing would you suggest?

Cheers

Mark

These are the settings in a pair of Webers that I recently sold which were set up for a 2.4 engine :

30mm venturi
55 idle jets
125 mains
F26 emulsion tubes
180 air correctors

& these are the settings in the Webers on my 2.5 litre twin-plug engine - they might be useful as a comparison (compression ratio is 10.3:1).

36mm venturi
55 idle jets
145/155 mains
F26 emulsion tubes
180/185 air correctors
