LM 2 readings

Post by udidwht » Sat May 17, 2014 7:26 am

Here is a run on the freeway at 55-58 mph 4th gear (3rib 002) 3000-3300rpm's. 405 northbound from Sunset Blvd. to Bellevue, WA. It isn't completely level/flat more like rolling hills. LM2 run is one continuous run from 1 thru 3.

Thoughts/suggestions?

Current jetting: 50 idles, 120 mains, 180 air correctors, F11 tubes, 28mm vents (float height 10.45mm Drop 32mm)

Just to add:

LBI and I'm now looking at 12.9 - 13.1 -.2 when glancing at the LM-2.

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