I just purehased a 036 st a tag sale. I thiught it was a 311 at first, but it has older, 036 covers that I got to fit on.
They didn't have the choke linkaged in it, but I manages to jury rig one out of .062 wire.
Now the saw starts and runs, pretty strong. Idles well.
At high speeds it runs strong, then stumbles, then comes back.
I tried running it with the cap loose, to check the venting. No change.
What are some ideas of what could be going on now?
As I writh this I'm thinking of Fuel filter, Gas line problem, Ignition module gap.
Are there more things that this saw in famous for?
