Weber 38/38 jet size..? May 25, 2008 21:00:50 GMT -5 Quote Select PostDeselect PostLink to PostBack to Top Post by hydroli on May 25, 2008 21:00:50 GMT -5 I finally started the engine, After having problems with the oil, which been trown from the engine by an incoherent fitting, I've been able to take a ride! It doesn't worked like I expected. The plugs are black as charcoal. After discarding a hypothetical barometric pressure drop, I figured that it could be caused by too big jets! What should I start with in my tuning while using a Weber 38/38 ? I have a mild lazer cam, nothing big, and a HO manifold.Thanks in advance for your clues.
