Reply to "Carb Fuel Leak - Need Some Help"

The key to sorting out jetting, Brian, is to realize it's not all that hard, approach it methodically and only make 1 change at a time. It's a bit of a time consuming process, as you change a jet 1 step (up or down, depending on what you're doing), put it back together, drive it for a little bit and then re-assess. It does take a while, but it's surprising how close to optimal you can get without a wideband air/fuel meter.

Resist the temptation to play with the mains/airs and only work on the idle circuit first. John C (Aircooled.net) actually recommends taking out the main jet stacks so you're only driving on the idle circuit. Usually the idles are pig rich (even "jetted for you" carbs will come rich), so you start out very simply- putting in smaller idle jets until it starts to run rough, and then going back up 1 so it runs smoothly. When you're ready I can direct you to some good write ups. IIrc Danny P has put some great dual carb info (rebuilding as well as jetting, I think) in the knowledge base. Some more reading- Aircooled.net's technical articles. Al
