When buying a used carburetor, look it over carefully for signs of trouble. Then buy only from sellers that will take refunds. Most wrecking yard will refund the price if it turns out to be faulty -- but ask first.
Overview
Look for:
* Air cleaner stud threads not damaged * Screws look new, not over tightened, distorted * Shafts are tight * Grease/oil is OK, it will clean up * No rusty linkage * Throttle opens fully
Bad - air cleaner stud broke off
Screws - should look good, not reefed (overtightened/distorted)
Throttle blades should open fully -- not stuck
Greasy crud can be OK, if it cleans up. Avoid Rusty crud.
