Without a picture it is hard to tell just what you are talking about.

There should be one line from inside the fuel tank to the pump side of the carburetor. This line connects to what should be a little plastic elbow on the side of the carburetor towards the cover plate held on with one screw,.

There should be a small line from the bulb returning to the tank. And another small line going from the bulb to the carburetor.

There is possibly an impulse line from the engine to the pump side of the carburetor cover plate? This should connect to a metal tube that connects to the cover plate with one screw holding the cover on.

I'll try to look at your illustrated parts list and see which hose is which?
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .

Sounds like you're on the right track. There are a couple things to remember about primer bulbs. First, they're set up to draw gas gently into your carb, NOT to pump gas in. That is, gas is gently pulled into the carb when you let off the bulb, not when you push. The idea is to protect the fragile parts inside the carb from the fumble-fingered he-man attentions of all us junior Paul Bunyans. When you push, all you're doing is ejecting that gas or air in the bulb into the fuel tank.

So, there should be a fuel pickup line (with a filter on the tank end) going directly to the carb, NOT to the primer bulb. There should be a (usually short) line from the carb to the primer bulb. And there should be a return line from the bulb to the tank that terminates just inside the tank, usually up high in the tank.

Oh, and hi all. New here. Cool site!

Welcome Tbone. Check your PM I just sent.


Thanks for sharing info etc with us. Have at it and enjoy.

 This site is all free  and is about helping and learning no matter the saw brand etc.  Just my way of giving back.

Thanks for the welcome!

Oh, one other thing about primer bulbs -- they are NOT necessary for the saw to run. They are merely a starting aid, designed to save you a few pulls on the rope. I have run many saws and other 2-cycle stuff with **** or broken primer bulbs. Yes, they're nice, but when one cracks or breaks, it ain't the end of the world.
