Customer Question

What is the gap between the magnetic col and the flywheel. The handbook has no mention of this circuit. This is the cs 370 chain saw with gas motor by echo.

Hi my name is ***** ***** welcome to Just Answer. The rule of thumb is to use a business card . Have the flywheel set where the magnets are pulling the coil in to it . Place the business card between the coil and flywheel and let the flywheel pull the coil to it . Tighten it down and then turn the flywheel to remove the business crd and the gap is set

Hi did you get the coil gapped ?
Customer: replied 1 year ago.
I was expecting a figure like 0.020 inches because a card CAN VARY FROM 0.003 TO 0.050 as I found when I went to set it up. Used 0.02 quage
Thank you It did not help to find the problem with the motor.

What exactly is the engine doing ?
Customer: replied 1 year ago.
I do not want to spend more than I have to, The coil assemble was loose hence the need for the gap. set with a feeler guage to set it to 0.02.
The pr0blem is that it runs for a short time and is difficult to start.

Have you checked the compression before starting and after it dies ?
