OK, next step is to synchronize the carbs. A tip: the front manifold's vacuum 
nipple has a plastic cap. It's difficult to get to.

When you take the carbs off to drill out the pilot screw anti-tamper covers, 
adjust the pilot screws and adjust the shims on the needles, permanently connect 
a piece of plastic tubing to the front vacuum nipple and bring it out to the 
left side of the engine where you can get to it next time. Plug it with a 6mm 
bolt when you're not using it to balance carbs.

Balancing: carb stix work very well.
