Default pinch test for the low end needle

How do you pinch the fuel line gentle or try to pinch the engine fuel line enough to cut the motor off. I need your help please tell me the right way how to do the pinch test for the low end needle.



Thank you

You need to squeeze it hard to stop the fuel from going in, the motor should run for about 10 sec.

refer to PINCH TEST 01... it says... pinch near the carb.

refer to PINCH TEST 02... somebody said... in the middle.


so... esham and james-Y... where did you PINCH your tube?

middle of the tube or near the carb?

logically.... pinch NEAR the carb... coz if your tube is LONG... then you pinch in the middle.... means you will have MORE fuel to burn. if you pinch NEAR the carb nipple... it doesnt matter how long your fuel tubing....


am i correct?

and emmm... thanks for the link esham!!!
