I'll increase my main jet size, get a Bing manual, and now I am reminded that the needle has to go up to increase flow in the midrange if needed. I'll do the main jets first. don do not archive ----- Original Message ----- From: Larry McFarland To: stratus-list@matronics.com Sent: Saturday, November 27, 2004 8:17 PM Subject: Re: Stratus-List: carb jets --> Stratus-List message posted by: "Larry McFarland" > Don, What you describe is detailed to some exactitude on page 18 of the Bing Carburettors Aircraft tuning and parts manual. Picking up power with the enriching circuit (choke) suggests you're running lean if the EGTs are reduced. If you lower the needle, you will lean the engine further and risk damage to the engine. They recommend doing only one thing at a time. I'd consider just another size jet first. I'm using 170s and my needle is on 3, one notch from the richest setting. Not being satisfied with trying to estimate by EGTs, I'm going to purchase a Colortune plug from Bing Monday. Then it might be possible to see better what these changes do. Yes, a main jet change will affect the midrange. It sound like you need the manual from Bing. Their phone number is 1-800-2464 weekdays 8:30-5:00 CST.

How bad a job IS that, anyway? Do I need gear pullers and an arbor press, or is it not that complex? Danny W.
