Hello. I'm new to the forums here but have been reading and learning a lot. Thank you.
I have a pair of Weber 40s I plan to use on a 2056 I'm building. The carbs are used, and I don't know how they're jetted. Can anyone recommend a base line? I'm at an altitude of 486 feet. I appreciate any suggestions! Steve |
