I have no saw problems.. but want to learn what the impulse line is ?? Is it a vaccum line ? What does it do ?
Plenty of saws have it run as a separate hose rather than through the carb body. Stihl 029/039/026/036/044/046, Husky 346/372/395 etc. all have one.On all of my 2 stroke saws etc, the impulse line is a passageway from the carb flange into the face of tbe carburetors. Do they have them with a separate hose on some saws?

However all my Macs and Homelites are like you said and run through the intake block to the carb.
I honestly don't know why, but I have noticed that of the one's that go through the intake to the carb are clam shell design rather than split case and are horizontal rather than vertical on cylinder (the one exception to this is my Super EZ which isn't clam shell) I haven't gone into my Super XL enough to see if it is clam shell or not. I don't know if that has anything to do with it or not.I'm curious what is the advantage of that arrangement versus the simple port on the intake flange? A stronger impulse on the carb diaphragm?
I would think it has more to do with the anti vibe that the boot and impulse line give things,
but I am just guessing.
