OK, I know, singles forum.......
The Bonneville is popping in the exhaust and generally not feeling it's usual go anywhere self. This has happened before, but usually close enough to MOT day fro me to let someone else do it. Two mechanics said the carbs needed balancing. So, I've ordered a pair of vacuum gauges. I've balanced carbs before, but only on a Ural where the adjustment was simply twin throttle cables.
The plan is:
1. Construct vacuum dampers as per instructions in gauges
2. Warm engine
3. Connect gauges to take off points on top of the carb stubs.
4. Set engine to run at just above idle via a large O-ring between the throttle and the housing.
5. Turn the screw awkwardly mounted between the carbs until both gauges read as close to each other as they'll go.
6. Swap the gauges left to right and check any difference between the two follows the gauge.
Is there anything else I should know about this? Any tips anyone would care to impart?
Cheers
