What's the best way to go when buying carb sync gauges? There are two gauges, one with two needles or electronic ones like the CarbMate.
Many thoughts on this of course. And since they are BMW carbs (Bing) the standard route is the motorcycle method. Personally, I bought a used MP gauge off a wrecked twin from an aircraft salvage yard. The advantage is they have dampeners already built in. You get the two needles to match and you're done. This is also shown as an alternative method on the Rotax Owners Association website. And you do want to balance them pneumatically even if they sound/feel good after your mechanical balance.

We bought a Synchromate for balancing the carbs on the Rotax's in our charge (UK Tecnam dealers).
Works a treat and personally, I find it much easier to watch the LED move than to watch two needles.
