Re: New Weber Carb Owner\'s tuning question
It idles ok in some circumstances, but not so well in others. If the engine is cold and I set the fast-idle cam and crank it then it idles fine at ~1500 RPM. But if I tap the accelerator to disengage the fast idle,or start driving, it drops down to about ~600 RPM at idle, and really struggles. Engine shakes so much that it shakes the PCV valve out of its grommet. Once the engine warms up though, it will run at the ~800 I set it to. If the engine is already warm when I start it, it will idle at the ~800 right away.
It seems I have three idle speeds rather than the two I can control with the screws: 1) fast idle at 1500, 2) curb idle at 800, and then 3) the crappy idle at ~600 if the engine is cold and it's not on the fast cam. I'd rather just have the two (800 and 1500) regardless of the engine temp! Could this be a function of automatic choke adjustment? If so, any idea how can I correct it?
Not sure what you mean by bogging, Brad, but it runs and accelerates fine when I step on the gas. Definitely a hp increase with this new carb!
