Hi John,

Your blower has an "EPA" carburetor. Starting in the mid 90's the EPA started mandating the emission levels on small engines. As part of this mandate the engines are tuned for emissions at the factory. The screws on the carburetor require a special screwdriver that the manufacture offers only to their repair shop network. They do this because, according to the EPA mandate, the manufacture is required to ensure that the carburetor stays within the emission specs. Therefore the manufacture only offers the adjustment tools to trained repair shops.

This said, I doubt that the problem with your blower will be cured with a carburetor adjustment. If the machine was running OK but now is not, something has changed. The carburetor will not go out of adjustment by itself. It sounds like the engine is not getting enough fuel. That would indicate that the carburetor is clogged with old fuel or dirt. I would start by cleaning the carburetor, cleaning out the fuel system (tank and hoses), and replacing the fuel filter. I think this will have you up and running again.

I hope this helps with your repair!

Hi Tom,

The correct fuel mixture is 50:1 or 2.6 oz. of 2-cycle oil to one gallon of gasoline.

It sounds to me like your trimmer may be suffering from a clogged carburetor. The carburetor can become clogged by dirt or other debris. The dirt may get by a damaged or missing air filter. It can enter through a crack in the fuel lines. Some tools use a foam air filter. Over time the filter itself will breakdown and create debris that will enter the carb and clog it. It is a good idea to replace the air filter at least once a year. If fuel is left sitting in an unused trimmer for more than a couple of months the fuel will begin to breakdown and go bad. As the fuel breaks down it will start to become gel like as well as begin to coat the internal parts of the carburetor with a varnish. The gel and varnish will plug the carburetor so that fuel can no longer flow through it. To get your trimmer running again you will need to either rebuild or replace the carburetor. When you replace the carburetor it is always a good idea to also replace the air and fuel filters. This helps ensure that more debris won't clog the new carburetor.

There is not a carburetor rebuild kit available for your trimmer. The carburetor will need to be replaced. The carburetor is part #308028007 and is available from http://www.ereplacementparts.com.

I hope this helps with your repair!
