Pinch test 4 stoke
This is my first 4stoker satio 120 and I trying to figure out how to pich test the fuel line for proper air fuel mixture. It this right...........
(with throttle wide open) Pinch and release the incomming fuel line and if.........
The RPM slows down and return to and idle the mixture is "Rich"
The RPM speed up and return to idle the mixture is "Lean"
The RPM stays the same the mixture is "OK"
Is this right?
