Stupid impulse hose installation question
« on: August 22, 2014, 03:58:42 pm »
I wish I didn't have to ask this, but I'm stuck on something that should be easy.  I'm trying to install a new molded impulse hose in an 026, and can't seem to get the @*&%! thing pulled through into the carburetor box.  With the crankcase and rear handle separated I started out by placing the engine-end of the hose on the crankcase nipple.  I then installed the rear handle to the crankcase, guiding the end of the impulse hose through the hole in the carb box as things came together.  The problem I ran into was, how to then get it snapped into place in the wall of the carb box so that the carb nipple doesn't simply push it out of the way?  I attempted to pull it in using a pair of pliers, which failed miserably; a ring of rubber tore off the end of the hose, and it still wasn't snapped in place!

I've ordered a new impulse line.  Any tips on how not to ruin it when it gets  here?

Those should pull into the air box from the cylinder side. Look at the "barb" on the hose for an indicator of direction. Use some soap or grease

I've tied a piece of package cord around the end of the impulse line to pull it through a hole. To pull on the hose makes it slightly smaller.

I think lube of some kind is going to be the way to go.  I also found a couple of mentions on AS about negotiating the carb end into its seat in the air box *before* assembling the handle to the case, and reaching in with forceps to attach the other end to the case nipple. 

I've done this before and didn't have nearly so much trouble.  The worst of it is that I was really looking forward to running the saw a little this weekend, and that isn't going to happen.  Oh well.

I do it ass backwards push the hose from the air box into the cylinder.
Give it a tug with a needle nose set of pliers to seat it, then use a long ass
set to fit it over the brass nipple.

For the record, I succeeded by lubricating with Murphy's oil soap (rinses away easily) and installing from the carb side of the box.  I had to use a blunt screwdriver to push parts of the rubber flange through, but it was fairly easy that way.  I then slipped the front of the handle/tank into place on the crankcase, and used curved forceps to get the hose onto the case nipple before installing any AV buffer screws.    Thanks for all the ideas.

Stihls are just so easy to work on?
