Folks,

As some will know, I pressed my /6 into daily driver status last week, and I guess it's been about 7 days. (while the car has been on the parking pad for quite some time, I've never "gotten to know it" much since it arrived) In particular, I've not driven a carbed car as a daily driver in years.

It does't run perfectly yet (of course), but I have a short story from yesterday. The day before yesterday, it started running crappy -- the 5 cylinder wonkle -- I had picked up gas that day -- hmm... -- anyway, here's the interesting bit. Having discected my webers a couple of times, I understand in principle how they work. Knowing that allowed me to get past my annoyance, and play with how the car drove. 5 cylinders at idle, but seemed ok on accel, and full throttle. Playing with spark plug wires isolated the offender, and pulling the idle jet revealed crap in the jet. Life is once again fine.

Things of interest:
a. in city traffic, you really do spend your life on the idle circuit. On my car, the transition is around 2800 or 2900 rpm. By 3K, you're well off the idles and onto the mains.
b. it really is the case that the transition can be felt. It's subtle if all cylinders are firing, but when one is out on one circuit it becomes more obvious. Once it was all working, I can still feel where the transition happens, but it is pretty subtle.

Back to your friday afternoon toils.

PS. All of this weekly driving has been with the roof off -- it's been in the trunk all week. I know you needed to know this. I needed to tell you. heh.

Dude,

You'll laugh. When I first owned Lyrssa's car, the FI drove me crazy. I had no instinct for it, and each failure seemed completely unintuitive to a seat-of-the-pants carb-guy. Eventually, I just replaced every line of hose on the engine -- a world of difference. Most of it was prolly orig, and there were many leaks that were fixed. The car was a "different car" after that. That was probably 7 years ago. I've lost my "carb secret squirrel" ring! It does have me digging for "old stuff" from holley days, and such.

When was the last time you thought about whether you were on the idle circuit or the mains as you were driving?

Now, I could be convinced to switch to EFI if it was attached to a 3.2.... heh (IMG:style_emoticons/default/laugh.gif)
