First Time Tuning a Carb (7 Easy Steps!)

I think it went well. I just followed the service manual instructions for idle mix and idle speed, and it was finished in no time. Basically:

1. Screw both idle mix screws inward until they gently bottom out

2. Unscrew them 1 or 1-1/2 turns

3. Warm the engine up for 30 minutes at 1200rpm (aka wedge a dowel behind the throttle linkage and look at diagrams)

4. Screw both screws inward until the rpm drops from lean mix

5. Screw both screws outward until the rpm drops again from rich mix

6. Screw them back in for the maximum rpm and smoothness

7. Adjust the idle

A quick test drive allowed me a fine adjustment later.
