Fuel pump impulse line.

[Nipper]

I have a Echo CS-520 I am having fuel issues with.
Is there a way to test the impulse line to the carb to see if its holding pressure without tearing everything apart to get to it?

I don’t know of a better way than to take the carb off and inspect your line.

Nothin to it but to do it.

Then pressure test it also.

We used to crank them up and spray WD 40 on the impulse line and on the carb boot. It would immediately die if either had a hole and was sucking air.

Theres something to it.....
Can't see where the line is going, looks like I'll need to remove most of the body to get to wherever its going.
I think I'll try a new carb first.
Thanks for the replies everyone!
