Need parts breakdown for walbro carb from my hb18010c homelite blower.does it make a diff. which line from fuel tank goes to either carb fitting with primer bulb??also have 2 xl-12 saws made in port chester n.y. got to be 50 years old..i have them running as good as my harley..what year did they leave n.y.??thanks fran

The short line in the tank (about 1/2 inch in tank) goes to fitting just below primer bulb. The other line that goes to bottom of tank with filter attached goes to other fitting.

hello sir,routing fuel line for craftsman,homelite,ryobi,hedge and line trimmers,fuel tank under engine, looking at machine from rear, shall fuel line on left with filter attached goes to bottom port of carb, fuel line from right side coming out of tank with inside tip attached goes to bottom port of primmer bulb,top line on primmer bulb goes to top port of carb, fuel tank under engine,fuel line routing,looking at machine from left side, left fuel line coming out of tank(drain back only) goes to right side small port of primmer bulb, left side larger fuel line from primmer bulb to top port of carb, fuel line coming out of tank (larger line) on the right side with filter attached goes to bottom port of carb, when replacing fuel line it is very important to use the same ID and OD line the homelite takes a special line that is black in color and a bigger size,the bigger line is ID .08-OD140 small line ID3/32 X 3/16.when the lines dissolve small pieces will get in the carb clogging small passages and screen,it is advisable that you clean out carb,and use a new filter.hope this helps,any comments welcome,thank you. if the filter has broken off of the line half way that is where you will run out of fuel, hh

From the pictures in the parts breakdown, this appears to be one of the newer model rotary-type carburetors. It is listed as part number 308028001. There is no mention of this machine in the Walbro carburetor application guide however. After viewing the picture and with the prefix of the carburetor known, you should be able to locate it on the Walbro website. I have the link to your machine's parts breakdown and to the Different Walbro models. Please view:

The fuel line from the tank fits to the main fuel inlet on the carb ( the inlet nearest to the alloy pump cover secured by a single screw), the other conection on the carb has a pipe that conects to the shortest conection on the back of the primer ( suction side ) a pipe then goes from the longer conection on the primer ( pressure side ) back to the tank, it just pushes into the top of the tank.
So to recap the primer pulls fuel from the carb, and dumps it back into the tank.

try running all of old gas out by spraying new gas into intake while turning over. otherwise, make sure the float is in operating condition

thats what it is try opening the gas lid look inside to see where the fuel line lies if its up high them try pushing it down to the bottom

I have Ryobi775r string trimmer with walbro WT526 carb. The fuel lines connect 3 parts eg. gas tank, bulb (mine is a separate bulb not part of carb.) and the carb. The bulb has 2 fittings- a short and a long one. The carb also has 2 fittings- one on top (vertcle) and one on the bottom (L shape). The gas tank has two holes in the bottom one for over flow line and the other for fuel inlet to the carb. This has a filter in the gas tank. Now the connections- connect the long fitting on bulb to the tank. this is the overflow. Connect the short fittin on bulb to the carb top (verticle) fitting. Connect the fuel line (with filter - it is in the tank) streight to the L fitting on the bottom of the carb. Make sure the fuel lines are of right diameter. Too big-and you will have leaks. You are done connecting the fuel lines. just for info. the bulb is there just to pull a vavcume in carb so that the fuel is sucked into the carb and is present there when you start the engine. Hope it helps. Good luck.

You need to know if it is a walbro or a zama carb. to start with.
then look closely at the carb. and find #`s
very small

walbro will be wt or wa then some #`s
zama will be c1q or c1u and some #`s on the opposite side of carb.
Walbro will be on the same side

you need to know the carb. #`s so a kit can be found for that particular carb. IE: complete kit or diaphram kit

I have seen 2 different carburetors used on this unit. A Walbro and a Zama. You will need to get the information off the carb. (Walbro WYC-10 or Zama K39A) are the two I have seen, but you need to be sure what yours is. Then purchase the correct O/H kit and rebuild it.

You need to rebuild the carburetor. Go to m-and-d.com then parts diagram then illustrated parts online then parts look up then under select OEM select Homelite then do as instructed. You should find the parts you need and hopefully the parts breakdown for the carb. this will help you in the rebuild. If it does not have the parts breakdown for the carb. find what mfg and model carb. it is then go to that site for breakdown.
