The fuel system on your chainsaw has a filtered inlet that goes to the input tube of the carburetor. The other hose on the carb is the priming hose. It runs from the carb outlet to the input, or suction side, of the primer bulb. The last line runs from the output side of the primer bulb back to the fuel tank.
It is the return line. When you prime your saw the primer pulls filtered fuel into the carb, to the primer bulb and then returns excess back to the tank. To find the suction side of the primer bulb, attach a piece of fuel line to one side of the primer. Now put the line in a small container of fuel. If you see bubbles when you press the bulb, the hose is hooked to the outlet side of the primer.
If it sucks fuel into the bulb then you have found the suction side. Identifying the input and output side of a carb that has a remote priming assembly can be very difficult and there is no rule that applies in every case. Usually you just need to use trial and error on those connections. If you have hooked everything up so you are pulling fuel through the carb, not pushing it into the carb, and your saw won't fire, you should just need to swap the lines on the carb and then it should run fine. The important thing is that you have the priming lines setup to pull fuel through the carb.

Installing new tank lines can be a bit challenging until you think about it backwards. Start by taking your new fuel line, part #, and insert it into the hole in the tank from the outside. Use the full length of hose. Do not cut it shorter. Feed enough line into the tank so that you can fish the line back out of the tank through the fill hole.
Now install the fuel filter, part #. Now that the filter is installed pull the line back into the tank until the filter is sitting in the bottom of the tank with a little slack in the fuel line.
Now measure the amount of line needed to get to the carburetor and cut it to length. I hope this helps! -UtahAV -Mark.

I had the same problem and I finally was able to get the spring back into place. What I wound up doing is coiling it as small as possible in my hand (which is very hard to do) and then carefully placing it in it's place on the housing.
If you can get most of the coils into the housing, then you can temporarily place the rope holding pulley in place and slowly wind until it removes the tension on the outside part of the spring. This will allow you to place the outer end of the starter spring into it's slot. I'm sure there is a tool or a trick out there to make this easier but I didn't have it!
Hi Ron, I would start with a general tune up. Replace the air filter (part #530037793), the spark plug (part#952030150), and the fuel filter (part #530095646). The carburetor may also need some adjustment. If you are not familiar with tuning a carburetor you will want to take the saw to a repair shop to have it done. You can easily burn the motor up if you do not know how to tune a carburetor. If none of this works then the problem will be dirt and debris in the carburetor and it will need to be rebuilt or replaced.
The carb kit is part #530069844. All of these parts are available from I hope this helps with your repair!
