036 Frankensaw

[Bob_w]

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?

First thing is to check P/C through ex port, check muffler screen while you are in there. Compression test. Pres/Vac test.

All the rubber parts ~30 years old unless they've been replaced. Hoses, AV mounts, wire insulation, intake boot, seals, carb guts, filters. Clean it up to see what you have.

Should be able to find used parts, try trading post, some 034 stuff will fit.
