How long should the choke be pulled out on a well tuned carburetor? I recently rebuilt my YF 2100S and also re-jetted the metering jet. It runs great and only needs the choke to be used for about 20 seconds just to start it up from a cold start. It doesn't seem like it's running rich. I've got the mixture screw turned out 1.5 turns. Just wondering what the consensus is on a well tuned carb and a manual choke.
