I gave up on my Weber's and got a set of Dellortos. Had them rebuilt professionally and have installed on the new motor (1.8 built out to 2056).
I can't get them running without covering the air intakes on the carbs. I believe I have a vacuum leak somewhere besides thecarbs or intake manifolds. Wondering if I missed some type of vacuum port on the engine itself. Anyone have a suggestion on where else air could be getting into the engine? |

When you say 'covering the air intakes' do you mean covering the venturis? Like all 4 at one time?
The Del manual from CB sucks. BIG time. Wasted money. Is there a better manual out there? |

Is there a better manual out there? Putting my hand over one of the venturi's makes a significant difference. The issue is that it works on either carb. That's why I think there is a leak someplace else. Is there any port in the block or head that maybe I didn't plug? |
