LM-2 readings

Post by 72Hardtop » Thu May 15, 2014 4:05 pm

At LBI the bus hovers right at 11.3-11.6:1 consistently.

Running around town in 3rd at 30mph (steady) and it's at high 12s - low 13.s

Getting on the throttle and it will go rich (not a lot) and then steady out to the above numbers. (around town).

Had a short freeway run and watched the gauge and it seemed to hover right around 13 - mid 13's. 4th gear 50+ mph. Again going say from 50 - 60+ and it will richen up then settle back down.

Going for another run here shortly and get some logs at different states.

So far it looks as if I might have to drop the idle (50) just a smidgen perhaps to 47-48. Rest of the carbs are at 120 main and 180 air correctors and F11 tubes.

City drive...traffic/lights (148th Ave NE - 148th Ave SE Bellevue, WA.) then some 3rd gear at 30mph on/off throttle with ease. Towards the end I believe I dropped a gears at times (traffic) easy with throttle.

Update:

I reset the carbs for LBI and glancing at the LM-2 I'm seeing 12.9-13.1-.2. (Looking as if 50 idles may be the ticket).

Taking off from a stop it will go rich to about mid-high 12's then settles around 13.2 - 13.6 or 7 (3rd gear 30-40mph).

On the freeway again at 50mph and up I'm seeing mid-high 13's to low-mid 14's (gradual rolling hills on freeway (405).

Grade on 405 southbound freeway (Kennydale Hill) I'll see high 13's to low 14-14.2 at 55mph 4th gear.

To be continued...

I don't think it's to bad either. I'd like to see perhaps a smidgen richer up top when running 55+. It'll hover or flirt with low to mid 14.s up top currently. Maybe a drop on the air correctors to say 175?

Gonna need to verify my vacuum as well. Need to confirm what if any I have while cruising the freeway. Gonna buy a length of hose that will let me see my vac gauge while driving. I'll T it into the system between the distributor and T for the carbs.

Sorry Colin, is it that they are to small? Clicking on the pic will expand it. The numbers on the graph at the left (right side) are the AFR #'s numbers. On bottom left to right are time. Sorry no tach set up yet.
