I just bought a 318 that had a surigng problem, cleaned the carb, new gas etc... and got that fixed. I checked the high speed RPM and it was only about 3100rpm. I can't seem to find a high speed adjustment screw, so I just adjusted the governer spring in different configurations untill I got it right betweem 3400-3500rpm. Is this the proper way to adjust the high speed? I did see the idle adjustment screw.

Usally the clamp that hold the cable to the motor needs to moved toward the motor to get more speed.

The throttle clamp and the different governor positions combine to find the correct high and low idle. Sounds like you're alright though.
