Craftsman Model #358.356080 Chainsaw

I am trying to replace the fuel lines on this model saw. Can someone please give me a diagram of the lines or tell me how they run from the tank to the carb? The tank has two holes in it for the lines but only one port on the carb and no primer bulb anywhere that I can see. Please help!MH

As you're holding the chainsaw with the bar pointing away from you:

The smaller hose on the primer goes to the lower pipe on the right side of the carb.

The larger hose on the primer goes into the fuel tank through the hole on the top right of the tank.

The smaller hose from the top left of the fuel tank goes to the top pipe on the right side of the carb.

The fuel filter attaches to the smaller hose after you've pulled it through the top of the tank.

One line runs from the carb nipple - underneath the carb - into the notch of the frame and through the tank hole that lines up with the notch. The fuel clunk/filter connects to the other end inside the fuel tank. Total length about 8"-10"

Another piece of line serves as the tank vent and connects to the duckbill checkvalve. Total length about 3". The vent line passes into the fuel tank through the other hole (furthest left and rearward) - the checkvalve connects to the end inside the tank. Push the checkvalve/fuel line up to the interior edge of the tank as tight as it'll go.

The other end of the vent line is cut at a sharp angle along the length of the line (tapers) for approximately 1/2" in length - the tapered end just lays in the upper portion of the frame at the top right of the tank.

Edit: One foot of tubing will do the job. Both pieces of tubing are the same size...

In response to question in Link #4 above....

Just the standard tips...

Check, clean and/or replace the spark plug

Clean air filter (very important)

Check and clean muffler/spark arrester assembly

Use fresh gas (treat ethanol-laced stuff with Startron)

Use quality 2-cycle oil - mix 16:1 (Bonus Tip: Use 1 oz. oil with an empty 16 oz. screw-top beer can - fill and shake for a perfect amount for small sawing jobs)

Follow starting instructions - set ignition switch to start, set throttle lock, 3 pulls on full choke, switch over to no choke for the fourth and subsequent pulls.

Beyond these you could have carb and/or tuning issues. Good luck.

Sears 358.356070 saw with Walbro carb no primer.

The line on top of the carb goes through the hole under carb with wires and connects to the crankcase to provide pressure/vacuum to pump fuel. Access is by taking top cover off.

A line goes from the pickup in the gas tank to the carb left side.

A vent line 2 - 3 inches goes from flap check valve at tank up behind carb with porous brass plug at end.

The 2 lines in tank are pushed in from the top and pulled up. May need to enlarge holes. About 20 inches of line is used
