Here's the scenario:
Case # 1: Merc triple (2 carbs) suddenly sagging badly while on plane. Stuck my fingers into the lower carb (hood was of) and it picked right up and ran normal. Removed my fingers and it sagged again. Repeated this several times and the condition eventually went away. Ran fine the rest of the day, but screwed up again the next time out and would not go away. (End of season.)
Case # 2 (same boat but with a Mark 78: While on plane, motor started to sag badly. Made a LEFT turn to go back to the landing and it cleared up and ran fine--until I ran straight forward. Did the left turn fix again and the problem went away. Repeated the maneuver a few times and the motor ran fine the rest of the day.
Case # 3: Newly rebuilt triple installed on the same boat with the LU in a barrel: Motor would start only with a shot of ether, run 3 or 4 seconds and stall. Another shot of ether and away it went again. Over and over again. Rebuilt carbs, changed ignition components, etc. No difference.
Okay, so what is the common problem responsible for all these of these irritating difficulties (since proven correct)?
