Before we go any further, lets see what your current jetting for the Weber 40 DCOE is and then we can check what needs replacing and where it's okay to use that size, following info is needed. Download a file of the strip down of the carb and check where what sits and then let us know, we can take it from there then.

air jet

choke

idle jet

We'll also need your proposed or current engine spec as this will play the biggest part in what jets and emulsions you'll need for your motor

Great thanks.Will send you the specs once I strip the carb.
