Chainsaw Repair

Fuel line replacement on these isn't too hard.  I remove the flywheel housing and flywheel.  Then you can route the fuel line down from the carb box, through the two little cast-in guide loops above and behind where the flywheel sits, and the back to the fuel tank hole (and into the fuel tank).  Those guide loops keep the line away from the spinnin' flywheel.  I use 3/32"x3/16" fuel line on these saws.  You can use .117"x.211" line too, but it's a tighter fit through the guide loops and the pass-through holes. 

The usual tricks of cutting a ^ point on the end of the line, melting a hole through that point, and tying some thin gauge wire through that hole (to 'fish' through the holes in the saw and pull the line after it) as well as oiling up the OD of the line when passing it through work well here.

I usually replace the crank seals when putting new fuel line on a saw that's been sitting for years.  Heck, the flywheel's already off.  The PTO side is easy to get to as well.  Just gotta spin off the clutch.  530019051 is the Poulan # for the crank seals.  Got my last set from my Husky dealer.  Chicago Rawhide/SKF 5510 works fine too.  Same seal on both sides of the saw.

The white portion is synthetic.
