Question: Walbro WyC-10 Carburetor
When I work the purge valve, the fuel does not go thru the carburetor and out the return but squirts out of the main jet by the butterfly valve. The purge valve does work fine if I take it out of the carburetor circuit. Engine runs only momentarily till it runs out of this splashed in prime. I have had the carb apart many times and cannot see the problem. What is it?
Question: Fuel Tank Assembly
Received PN 308123015 ( Fuel tank & Cap Assy) I comes with the two plastic tubes attached, but does not have the in-tank filter that my UT08544 Blower had. Is the in-tank filter no longer used. I thought the tank assy would have included this filter as there seems to be no way to install it without removing the hoses from the tank. Not a good idea I would think. HELP?
Question: Running Slow
My blower only runs with the choke on (and it runs slow). If I turn the choke off the engine will quit running. I changed the gas hoses and fuel filter but it made no difference. What is wrong?
Reply: Running Slow
It sounds like your trimmer is not getting enough fuel, probably caused by 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 engine 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 engine 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.
Homelite does not offer a carburetor rebuild kit. They do offer a new carburetor. The carburetor is part #308429001 and is available from http://www.ereplacementparts.com.
Good luck with your repair!
