Carburetor Assembly 530071822

This process looks long but I assure you it is super easy and takes no time at all. If this is your first time taking a fuel system apart take pictures or use a IPB so you do not have to rely on memory for reassembly.

1. First I drained and disposed of all the old fuel.

2. Then I removed the fuel filter from the intake hose in the fuel tank with needle nose pliers. Once the fuel filter was removed then I remove the return line fuel assembly pickup (fancy name for little plastic insert) with needle nose pliers.

3. After both the fuel filter and fuel assembly pickup was remove then I removed the gas tank carefully, thus not to tear the fuel lines. The fuel tank is held on with two star screws so you would need the proper star screw driver or ratchet attachment.

4. Next I removed the hoses from the carburetor also careful not to tear the fuel lines. The reason for such care is because I used the old hoses to determine the size of the new hoses. Now for the carburetor.

5. I removed the air filter and air filter cover there are two Allen screws that hold on the carburetor. Using a the proper Allen key I remove both screws. Be careful not to tear any gaskets when removing. Also the throttle cable to attached to the carburetor it is easy to remove just angle the L properly and it slides right out.

Now that the carburetor is removed assess the situation. In my case I took the carburetor apart to see if I could clean it before I ordered a new carburetor but this was beyond cleaning. If you have never taken a carburetor apart proceed with caution and read a different repair guide.

Most of the parts where rusted and gummed and for 25 bucks I simple decided to order a new one. Also since I had the fuel take off I cleaned it and ordered new hoses, fuel filter, and a new fuel tank cap. I only ordered a new cap because the other one was cracked.

6. Once the parts arrived I began by cutting the new fuel hoses. I used the old hoses to determine the size. NOTE: Cut the new pieces a little longer than the old ones because the hardest part of the project is putting the new hoses into the fuel tank. And unless you are really good you will tare up the ends a bit and will need to be cut off. Plus you will need to cut the new ones at an angle so you will need to cut that flat as well.

7. After the cut is made, cut the end of the hoses at a sharp angle thus to be able to put the tip of the hose through the holes int he fuel tank. I recommend using a little lube on the outside of the hoses as well just so they slide easier. In my case I used a little 2-cycle oil because I knew it would not contaminate the line or the gas in the fuel tank. Once the hoses where just barely through the hole I grabbed the end of the hoses with needle nose pliers and pulled the desired length. On the intake hose I cut the end flush and attached the new fuel filter then put it back into the fuel tank. Also cut and attached the return line fuel assembly pickup to the return line then pulled it up to the top of the fuel tank.

8. Before I attached the tank I put the new carburetor on the same way I took it off making sure to attach the throttle cable as I went. When the screws where in line I tightened them down snug. Do not over tighten.

9. Now I attached fuel tank in same manner not to over tighten the screws.

10. Finally I attached the fuel lines to the carburetor filled the fuel tank with good 2 cycle and closes the fuel tank with my new fuel cap. Attached the air filter and air filter cover and we where good to go.

Primed the carburetor, put it full choke, cranked a could of times went into half choke. It fired right up, went to no choke and gave it full throttle and she purred like a kitten. Okay it is a line trimmer she roared like a lion but either way it is working great.

Opened the air cleaner and removed 2 screws and 2 hoses. Reverse order to install, fired up right away.

As I have done in the past while repairing tools or anything that I am not familiar with. I take plenty of pictures of everything as a take it apart. Then use the pictures to put it back together. It hasn't failed me yet. It may take a little longer to do the repair, but so far it's done great for me.

Don't get in a hurry and if you can't remember where things go take pictures before and during disassembly.
