I pulled the carbs to install a new linkage, and blew out the jets while I was at it. The two carbs are synchronized with each other better than they've ever been, but now there's a discrepancy within one of the carbs (DRLA 45s). I'm wondering if I bent a throttle plate, or if there's something else I did that could cause this?
The lower one is cylinder 3, if that matters. There was a slight discrepancy before, but now they're further apart.  |

With the carburetor on the engine, I was not able to perceive a difference in the butterfly opening.
Running the engine and squirting water around the carburetor to manifold connection, I was not able to change the way the engine was running. I wasn't able to reach most of the intake manifold to engine connection with the spray bottle. For lack of another idea, I tried swapping the idle jets between the throats. No change. |
