In the process o trying to get the car to run smooth I have removed the jets from my Webers.
If I understand this properly there are three pieces: tube holder, jet, and cap. As I removed them, one jet had come out of its tube holder and was sitting in the carb. A little coaxing and pressing and I was able to remove the jet fine. I thought I would squeeze the tabs on the holder a little so it would hold the jet better; but in doing so a tab broke off. metal seems very brittle. Tube can hold jet ok but I think I need a new tube...are these available? If the jet was not pressed tight into the tube; would it affect performance?  |

Agree. Use the "Lean Best" method to tune before playing with changing jets. It can be found on Paul Abbots site. www.performanceoriented.com. Make sure your engine is at operating temperature before tuning.
Clean with... Carb cleaner and a brass brush. |
