I have a Craftsman 16 inch, 36cc, model 358.351061 chain saw. The fuel line broke. So I decided to replace all the lines. There is a large and small diameter line. Now it doesn't get fuel to the cylinder. It has two lines to the fuel tank. One large diameter the other is small. I'm not sure I have them connected properly. The primer bulb has connections for a large and small line. It also has markings for tank and carb. The carb has a large and small line connections. Any help would be appreciated. Thanks, Tom

The second carburetor port feeds the primer (bleeder), returns excess fuel to tank.
Filtered line to carb, carb to bleeder, bleeder to tank (probably not visible and no hose in tank).

The print is deceptive, it appears the filtered line feed the bleeder it does not!

just connect them both anyway you chose. press prime button a few times to pressurise tank. you get a 50/50 chance to get it right.
if it just sucking air release pressure first by removing filler cap to prevent face full of fuel then swap pipes over on carb. i did this job a couple of weeks a go on my husky66. only use proper flexy pipe from a lawn mower centre. costs about £2.50 / foot.
