Sounds like you already have a manometer to measure the difference between the front and rear cylinder and you know how to read it, so I'll skip some of that. Set the idle speed first. Check the gauge readings. If the difference is less than 2 cm Hg, the carburetors are considered synched. If not, the carburetor butterfly adjuster bolt on the rear cylinder is adjusted. Turning it in will increase vacuum in the rear cylinder and turning it out decreases it. After the vacuum readings are close enough, the idle is checked again.
