Hello
There are many on the net. Here is a good link.

I know of no diagram available for this. But if you have both lines out and visible you can just put them on the carb, fill the tank and prime it and see if fuel moves. If it does your done....if not....flip the lines and try again!

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:

I don't have a diagram or the part numbers to the minor and major repair kits, but a Stihl dealer should be able to help. Tell him you need a kit for a ZAMA C1Q type carb. The exploded view should be with the kit.

Here are various graphics from the B&S Intek Twin governor. Maybe they're close . . .

Either clogged or needs cleaning/ rebuild. ITS SIMPLE! ok If you have a Walbro WT series carb "without" a built on primer bulb here it is. First off if the fuel lines disintegrated you MUST disassemble it and clean it out. The MOST infintesimle speck of gas line trapped, can allow good prime and bad operation. OK? Don't be lazy on this. Just be delicate removing the flaps gasket and diaphram. ZAMA GND-12 Is the replacement Gasket and diaphram kit fot that carb. Use a cleaner, compressed air or blow good thru it. OK Now...Primer bulb, Carb, and Fuel tank, re connects: Smaller Diameter line comes from Gas tank (Connect filter screen to this in tank) to the short Straight brass carb connector. Primer bulb suction goes to the bent carb brass connector. If small line brings fuel "in" this other line sucks it back "Thru the primer bulb" and the blow side of the primer bulb sends it back to the fuel tank! So...Small Line brings fuel "TO/IN" carb thru short brass connect on carb. Other carb connect goes to bulb suction "IN", Then primer bulb "Pressure OUT" goes thru the larger tube "back to fuel tank". Trust me I know how frustrating a simple diagram is to find online fo this set up. And if you have a carb problem on top of the hook up uncertainty you got frustration. Not only was online help hard to find (Mfg...etc NFG at all!) My local repairshop in BBrook NJ could not tell me how!!! and thats no lie! Walbro has a "generic" carb diagram but no "hook up info" specifically. Poulan don't list it either. And these things routinly fall to pcs. all 3 of mine crumpled together on yr. 3 of use.

need to know which feul and which is return

Don't have a diagram. It's pretty simple, tho.

There is a throttle cable run from the throtle control lever on the dash down to the carburetor. There is a lever on the carburetor -- usually this has a hole in it where the end of the throttle cable hooks.

There should be a clamp in that vicinity to hold down the throttle cable housing to allow the cable inside to move back and forth without moving the cable housing,
