Husqvarna 225 B Blower

Hi -
does anyone please know how the fuel line(s) run? I mean what path do they take between the tank, bubble, carb (bottom and top) , return to tank.
Thank you in advance for any help.

The line with the filter on the end in the tank goes to the inlet side of the carb. One fitting on the primer sucks air in when you release the bulb. This goes to a line that runs to the return fitting on the carb. The fitting that pushes air out when you press the primer goes to the return line to the tank.

Thank you cheese for the quick reply. To follow up: the carb inlet is the top or bottom port on the carb?
Thank again .......

I don't know, depends on which carb you have and exactly how it's configured.

two of the lines are for fuel one tank to bulb one bulb to carb the other similar looking like is a "pulse tube" that energizes the the fuel diaphragm in the carb it is a piece of the same fuel line stuff why are you changing the bulb? worked on more husky stuff than I'd care to remember, fuel lines are common to rot out, but the bulb??

can't believe I am having such a prob! Dumbass I guess.Started off because the bulb cracked up, filter was rambling around because the line rotted in half Are you saying-filter in tank hose to rt bottom tube on carb ? top left nipple on carb to short stem of p bulb. Long stem on bulb line goes back to tank? I sure appreciate your help. Carb 1 q by zama

maybe review my link to the parts diagram will help visually, line from tank to bulb, longest connector, bulb shortest connector to carb, the bulb has a check valve built in to allow the carb to draw once primed, experiment with one hose off the bulb and see for yourself how it works, draws in one direction pushes in the other, good luck

I guess something like vent or something else is my prob. I did as you mentioned, all that seems fine, but it dies real fast, like 3 seconds or so and I have to keep it on full chock to try to restart. Replaced s. plug and looked at it after it started and died, dry as a bone. Have another suggestion?

sounds like a classic fuel line problem, when it dies is there any fuel showing in the bulb? have you changed the line? if it's getting steady fuel, time for a compression test - 90/100 psi just to start, more the better
