MAC3200 Chain Saw...

I'm having trouble replacing the fuel lines. The one from the tank to the bulb broke and the others are in bad shape. I need to replace them all. I also am having quite a time figuring out the trigger and spring assembly. (How to re assemble it).

4 Your primer bulb has a short stem and a long stem on the back of it. One gas line goes from the short stem back to the left side of the carb. The long stem of the bulb section is connected to the gas line where it leads back to the the fuel tank where it bleeds excess gas from the primer bulb. If you have the carb off. You will notice two vertical holes in the facing wall. The top hole is for the main fuel line that leads back from the gas tank to the right side of the carb. The bottom hole is for the gas line that is connected to the long stem section of the primer bulb which leads back to the gas tank. This one gas line is short and goes a 1/4 inch inside the tank. If you take off the gas cap you will see two vertical holes on the divider wall between the tank and carb section. Meanwhile the gas line conected on the right side of the carb goes in the top hole and goes thru the divider wallto the bottom of the tank with its fuel filter attached. I bought my gas lines at Home Depot-they sell only one type in the lawn mower section. I know lowes did sell the exact line but they dont carry that item any more. I bought my primer bulb at the local mower shopPart #683974 or walbro#188-512-1. The bulb cost $6.95. To get the fuel lines thru the divider wall, I used a short plastic tube that comes with a can of wd40. Feed the plastic tube inside the gas line and then push the tube and gas line very slowly thru the wall and then use needle nose pliers to pull the whole fuel line thru the hole down into the gas tank. I took pictures of my fuel line arrangement. Dont know to atch the pics to this section. I dont kow how to fix your other problem yet. I must mention that my work angle and directions are based from my position looking down at the attached carb with the blade pointing directly away from me and the handle in my hand. this is the arrangement in my mac3200.
