Bh25 le carb schematic

My BH 25 le leaf blower will not draw fuel. I replaced the rotted fuel lines, I noticed that the one return fuel line is blocked, air can not get threw it, looks like a waxy substance in the hole when I took it apart, maybe it is supposed to be that way. Help me please.

The waxy substance it gelled fuel. You have to totally clean and blow out all passageways. Resist using any hard tools or drill bits, you want to change NOTHING in terms of size..You just want it totally all cleaned.
Replace all soft parts. Verify the passageways are open. I prefer to soak in carb cleaner, it is strong and nasty, but resolves what you describe. Spray stuff seems to work well, but I worry about areas like venturi discharge systems...Soaking does it.

    Mike, thanks so much. I came to Thailand a few years ago, the blower always worked fine before. I usually put a little injector cleaner in the new fuel. The fuel here is not as good as in America. Thanks again Mike.

This part fits your Leaf Blower. Husqvarna fuel filter. If the fuel filter is clogged, it willrestrict the flow of fuel to the carburetor. As a result, the engine may not start.

How do I find diagram for fuel lines ?


You should have 2 lines, one supply, and 1 return. If you have a pump primer, it does NOT pump fuel into the carb. It DRAWS fuel thru the carb back into the tank, so its easy to tell which line is which, and also the supply line will have a filter on it.

Won't prime the carburator to start


If the primer buld is hard to push or wont return to shape like its supposed to then there is an obstruction in the carb. If it just wont move fuel then there is a hole in the fuel line or the fuel line is rotted off in the tank.
If the primer bulb itself is discolored ( should be clear not brown) it should also be replaced.

Need to replace both fuel lines on My BVM200 LE leaf blower, 1 large and 1 small fuel line, can You tell what size they are??


On your blower, it looks like the small line supplies fuel to the carburator which will be connected to the fuel filter in the tank, and the large line looks like the fuel return line.

Yard broom leaf blower will not stay running I


It seems that the carb is not getting fuel. It could be a cracked fuel line. The fuel priming bulb could also be cracked/dry rotted. Possibly the fuel pump in the carb is bad. The carb is rather intricate and not something anyone without training should try to repair. The overhaul kit will cost $15 to $20. I suggest you take the blower to a repair shop.

The fuel line broke and I noticed one only one connection from the carb and two from the fuel tank. I hooked one up and primed it and it ran. What about the other one coming out of the fuel tank? Thanks


One line is hooked to the fuel filter in the tank. It feeds fuel to the carburetor. The other line is a return line from the carburetor. The return connection of the carburetor is on the back side toward the impeller housing.
Good Day.

Which lines hook to what?


Fuel filter to bottom of carb. The suction port of primer to the top of carb outlet line to other port to tank.
To tell which port is outlet put your finger on one port and push bulb if the bulb collapses and doesn't return then that is the inlet (suction) side.
Good luck!
