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?

Your lean going into the transition.
About where is you adjustment screw on the threaded shaft for your accelerator pump? Is it about in the middle of the threads? More towards the end? What???? Clayton Clayton |

Oh wait a minute... the right side has less thread showing, hardly any... and that is the one that snaps. I guess they should be exactly the same, or is there a reason that they are not?
