Hi, wondering if any of you clever people would know the correct size needle valve for webber 40dcoe on a 1600 crossflow.
Thanks in anticipation Mike

Very little info in my Weber tuning manual
Looks like 1.5 to 1.75 will be close
I would post on Turbosports forum, they'll know.

Probably on the old Dave Andrews site - If wanting to play with webers you could do worse than read it twice.
