Triple Weber 42DCOE's on a 240

[Andy K]

Any know of a respectable shop who can tune Weber's? My top end is fine but have low to midrange issues on my 240.

If you roll up your sleeves and set up the carbs using the default settings in the Weber guides by Haynes or Pat Braden then you should be close.

I recommend matching your carbs Emulsion tubes to the list below (F2 or F11) rather than the choke size.  Hopefully your carbs have either 28 or 30 mm chokes and either F2 or F11 emulsion tubes.

Make sure the fuel levels are equal and set to ~ 29mm down from the ledge and that the linkage opens all 3 carbs at exactly the same time and same amount.

btw your 42DCOE carbs are very valuable and desirable by collectors. 40DCOE are the most common variant.

Here are the default settings for 28mm and 30mm chokes in 40DCOE''s

Here is a good reference for a well sorted 240z with Cam and slight over-bore: 

I foresee a great Weber tuning web page being ready by spring that will help you very much
