Wow all these suggestions instead of just fixing the problem.
I could be remembering wrong, but the fuel line from the tank the one with the strainer on it goes to the top of the carb, and to the bottom of the carb is a line from the primer bulb, and the other side of the primer bulb has the 2nd line going into the tank. If the lines are brittle and it as broken off instead of pulled off a nipple, that's a good sign that it is time to get some fuel line and replace it all. if it does need replaced, y You do not need some kit specific to that model blower, just correct diameter bulk fuel line and cut it to length.
I had one of those that ran fine for about a dozen years on plain E10 fuel. Granted, it might have been a generation where the EPA had not convinced 2 cycle manufacturers to lean them out as much yet. I recall getting a ~$15 aftermarket carb for it on amazon and it was trash with an adjust needle that had stripped threads so had to return that and get another replacement.
