Chainsaw Repair

+1

Yea I figured the owner will be happy to know that was all it was.   It took me about 40 min to find it and put it all back together and have it running.    That is another thing I have become really quick at tearing these saws down and getting them back together.   Just practice.

Worked on a Husqvarna 61 today.   Owner said it would start but not stay running.  First the fuel line was all **** and when pulled off the carb it fell apart.   The carburetor diaphragms were stiff as a board.   The gasket between the carb and intake had a big tear.   The gasket between the intake and cylinder was missing half of it. 
So replaced the fuel line, installed a kit in the carb, and made the gaskets.   Saw started, ran, idled good.

Next was a Poulan 3314 that I put a new pulley and recoil spring on.   Worked fine when completed.

Then there is this Shindiawa string trimmer.  It would run about 5 minutes or less get real hot and then die.   It would not restart until it cooled back down.  Checked spark and is ok.  Compression good before and after.   Did a pressure and vacuum test and is ok.  Put spark plug on top of cylinder and pulled rope and showed good spark.   Muffler is a catalytic type so tried replacing the muffler and no go.   Spark arrester ok.   Tried cracking the fuel cap open to see if it was venting ok.   Venting was ok.   Replaced the fuel filter and bingo that was it.   It seems that the filter would gradually slow fuel delivery down causing it to get lean overheat and then eventually die.   Ran it for 30 minutes straight with no issues and restarts on one pull every time.

Meant to post this here, not in its own thread.

Maroon 42cc poulan came in yesterday evening by a firewood cutter.  All covers bar chain etc off with muffler hanging.
While owner was still here. I seen both bolts T30 were still in there and gasket and heat shield was still in place. So I just tightened them up to make sure threads not all wollerded out in the cylinder. Said you put it all back together you can take it back now. No charge.

Said it had been trouble free for 3 years so far. 
 

I bet it got a little quieter afterwards.

Just to explain for the guy missing it.  It was those silver mufflers with 2 inside bolts with a outside cover over them with a single nut on a stud deal.
