Lean Burn

Also, you'll want to take a look under the cover on the front side of the carb. There are two adjustment screws. one is for accelerator pump stroke, the other determines how far up the metering rods are pulled. I adjusted my former LB carb so the pump had a full stroke and the rods were pulled as far up as possible. If there are problems, then back off on the adjustment. I had no problems.
