165 buck for a carb rebuild is highway robbery. 20 minutes labor and a 10.00$ carb kit. You can buy a new Walbro WT 194 carb with both adjustable high and low jets for around 65 bucks. If your 026 has a carb with a high fixed jet carburetor, I would search Ebay for the WT194. They are very easy to install. If you go that way you might as well replace the fuel and impulse lines and get a new fuel filter. Doing this is very simple to do. If you have any problems , type in arborist site into Google. Go to this site and click on the chainsaw board and you will find anything and everything in regards to your 026 by doing a search.My dealer does carb rebuilds for like 15 to 30 dollars. I kind of figure it was carb related. IMO though 165 is too much for a just a carb rebuild, are they doing any thing else to it?
