Ultrasonic cleaning of carburetors
Instead of hand-washing carburetors Mikuni or Keihin Volunteer immerses them in ultrasound solution Simple GreenThis removes the carbon from even the narrowest channels where the needle or compressed air can't reach, and the effect is that the motor is running smoothly at idle speeds.
-
Diagnosis by "heat map"
With help. thermal Igor scans the engine after 10 minutes of operation and detects overheated areas (such as a faulty cylinder or a clogged water channel), which detects problems that are not visible in standard diagnostics.
Interestingly, some of these methods Voloblovsky described in his free-guide (you can download the link), which also has instructions for self-diagnosis of motors Yamaha 8-15 hp.
Disconnect the battery (if any)
Pour out old oil (if you plan to repair the engine)
Take a picture of the motor serial number
Bring a spare fuel tank with clean gasoline (for post-repair test)
