WOW! Burb idles so much better. Before it was almost like I had a crappy camshaft. Loped stupidly. Now its just a nice constant idle. Seems like the thing on CFM-Tech saying about the motor cycling from lean to rich at low rpm/idle was quite true. Power when the motor is cold is far better too. Throttle response from idle is better as well. I should have done this a long time ago. Throttle response still isn't GREAT but its better. Still a little lag like I'm feeding it too much air. Sounds like my dad's race car did when the secondaries were adjusted way too easy.
