Chainsaw Repair

Well I finally put the pieces together I had rounded up to put this parts saw together.  I think this will be a nice small saw if I get it dialed in the way I want it.  I thought is was going to run ok pretty much in stock form, but I think I need to fix up some things.  I think the carb needs rebuilt, while I could get some adjustment out of the needles, never really got it where I wanted it.  First thing I want to replace is the impulse line.  I stopped at 3 local automotive stores to find reinforced fuel line with a 3/32 id, none had it.  5/32 was as small as they had so first question is what is everyone using?  When I stopped at the stihl dealer to ask about the weed eater fuel line, the guy's dad was filling in for the owner he points to a bucket with pieces of tygoon in it & says there you go, no thanks i say with a smile & leave.  I will try & post up some pictures this evening

Ill have to look around for maybe an echo dealer.  After he pointed to the tygoon pyle, he said pretty much the same thing with needing to order the special molded lines.  After reading up on this i had to laugh at myself.  Years ago I had a jonsered 920, you guessed it ran great until it half melted the make shift impulse line that would promptly fall off.

Kinda first for me, this saw had a little small clamp that was up above the barb, not sure why it was there (wasn't doing any good above the barb), but did these saws come with one of those squeeze it type clamps?

Seems the carb kits a little steep for the ol hda-49, i got another carb I'm gonna try out first.

I'd forgotten the Dolmar line.  Tygon type vinyl line is completely unsuitable for an impulse application because it will fail with the heat.  Rubber line is the way to go.  High temp automotive 'emissions' line works fine if you can get it in the right size.

That saw would have had a small wire spring clamp on the line at the cylinder end.  It probably slipped out of position or was incorrectly installed on that saw.

You know I know them part numbers for the stihl dolmar and maybe the echo lines used for impluse lines are in threads some where.

 I think we need to dig up the info and make a Impulse line thread and save it in the how to area.
