I looked at E tubes and F2 are going to be sent. Still deciding on a second set. We have to tame that lean spike at start too.

OK I think you are there. 13 AF +/- 0.5 If you want to go one step further, it will take another fuel jet and air corrector based on the data below. A 160 fuel and 230 air would be as good as it could get.

bummer.

You changed the "Caster" of rocks angle.

That looks great! 13+/- 0.5 for most of the run. I'll overlay it later today after church.

Excellent!

not enough caster can make it a squirelly .... careful!

Dig this *very* early one!

I guess the calibration must have drifted in past runs... oh well, it looks flat which is good. Yes please try the 155 again btw how does the butt dyno sense the rich lean changes?

The style is traceable to1967 designs.

Some may chime in about wheel spacers on the front.... or they may not...shhhhhhhhh

Here is the great John Coffey's recommended street setup. Front Toe: 1/16" to 3/32" in Camber: 0 to 1 negative with 1 being preferred. Caster: 4 to 6 positive. The actual number between 4 and 6 is not important, only that both sides are the same. Rear Toe: 1/16" in Camber: 0 to 1 negative with 1 being preferred. Track: Make sure the rear wheels track the front.

the carb above is an early one w/o bypass valve so a small hole was drilled in the brass plate as a bypass to balance air flow at idle.

Dan has a Canadian Spec 240z but he didn't mention his Canadian Spec Titan Truck:

Charles you got me. All the time you all thought that Blue was the colour of my Z:

Whats on deck?

That early Canadian spec 240Z is very rare indeed!

Yes. I agree.

Do you think the meter's calibration was off for the 165/225 run posted above?

Overkill but it has what you want: http://www.classiczcars.com/topic/39668-77-280z-drum-brake-refresh/

Thanks. It is stretched out more in the higher rpm range so I fitted each side and spliced. It looks like the run was offset towards the rich side again.
