Jonsered CS2150, identify somthin for me

[U&A]

is this an adjustment for the fuel coming up thru the fuel pickup hose and filter? Its on the tank. Clutch side of the saw just under the carb.

Cant find it in an IPL but thats the best I can gather from the marbles rolling around upstairs. Definitely feels like there is a spring or something behind it.

Thanks fellas.

I believe that one originally had a purge bubble so the original return line back into the tank is plugged. The one on the left is your fuel supply line, looks like the middle one is plugged, and the one on the right probably has an echo type tank vent on the end of it

Ok.

Really appreciate it Kevin. I went to turn it and it had an odd feeling so I left it and wanted to find out what it is.

Was just doing my normal clean up and checking bolts and screws for “tight” and just noticed that guy. Its a T27.

Ill see how it feels trying to give it a slight snug as it DID seem very loose. Im assuming by what you say it must be a corse screw threaded directly into plastic? So be easy.

I’m not really certain. I don’t remember doing it but I likely did. It’s possible that the middle one had a barbed fitting for the return line and I simply stuck a piece of hose over it and then a screw with some sealant on it in order to plug it off

I have one with the purge bulb, purge line goes back to the tank through the line on the right. Center is tank vent, left is fuel line.

I suspect yours has a "press fit" screw in the vent hole to seal it "well enough" & the purge return is probably blocked off up around the carb.
The Husky equivalents that never had a purge don't have return line on the right & the vent has a special plug (usually black & smaller than the one pictured here)
