There is usally a rod that travels under handle to carb. Could be a cable if its a top line saw. If you are having problem with it take top of saw body apart and it should give you access.

Some carbs have obvious adjustments ("H" for high speed, "L" for low speed or idle. )

Some however are hidden. Heres a video showing how to find theses hidden adjustments.

Most machines will have a z bend in the end of the throttle wire, the outer cable will be anchored with a square block into the induction block, the z bend in the cable will then fit into a hole in the throttle spindle on the carb, there will only be one hole in the spindle the correct size for the cable.

According to the manual, the gasoline to oil ratio for the Power Mac 320 depends on the lubricating oil. McCullough 40:1 Two-Cycle Custom Lubricant is recommended. However, any good SAE 40 two-cycle oil should be used at a 20:1 ratio. See page 7 of the owner's manual. This is available from ManualsLib, https://www.manualslib.com/products/Mcculloch-Power-Mac-320-3983820.html .
