Yes, the 6-channel version will work on engines with 2, 3, 4, 5, & 6 carbs or throttle bodies.
Note: When not using channels, leave them hanging freely. Do NOT cap them off.
Each digit represents 0.113 inHg. Note that there is an offset from atmospheric pressure of 2.823inHg (25 digits). That is why the gauge reads approx. "25" when the engine is not running. Please note that the actual values are not important for balancing carbs or throttle bodies. What is important is consistency (balance) between all the measurements. All the values should be within 1-digit of each other for accuracy. Doing this will ensure your machine runs at it's optimum and will likely synchronize your engine with higher accuracy than your local mechanic's tools will allow.
