Dual Dellorto carb setup, the carbs tend to snap under load. After tinkering for a while with airflow and linkage and not resolving, I am going to go to basics and check fuel pressure. How do I measure this? Is there an inline guage I can buy?

QUOTE(Twystd1 @ Nov 3 2007, 05:41 PM)  Try about 1/3rd from top of threads. If no worky...... Then 1/2 from top of threads... Somewhere in there is TYPICALLY what works. C Well, I tried both of those settings, and several in between. I drove it at each setting and I still seem to get that snap under load. I am starting to get really frustrated, so I am coming to the board for help. Help! Questions: 1. Is it the more you thread the nut down the threaded shaft, the more squirt your accelerator pump will provide, or the other way around? 2. What does it mean when, under load, you hear a sound from the carbs that kinda sounds like gargling? |
