Thanks so much.Appears to have a Walbro carburetor. It looks like on the WYLs but need the model number off the carburetor to be sure.
Currently I say it needs the Walbro 188-12-8 but without the model number it is just a guess.
I only need a fuel primer bulb. But thank you.Carb # 753-05908. Roughly $40.00. For individual part numbers we will need carb manufacturer and number. You will find these on the carb.
Which is exactly what I thought it was except you paid the Stihl price instead of Walbro or Stens 615-740 price.Folks, Thank you all for trying to help. I took the old bulb to a local saw shop and they matched it up, For those who wonder why that I didn't do that to start with, Since Covid, I try to stay home and order things that I need. For future reference the part # is 4133 121 2700 thanks again.
