Wow Greg. My gut reaction is WTH?
IMO At light throttle cruising the engine should be pulling a heck of a lot harder than that.
I'd expect a minimum or 14"Hg and as high as 18"Hg depending on rpm, speed and whether a slight up downhill.
Um, can I ship my *** over there so you can kick me in it?
I put the paper clip on the secondaries vac can rod to make sure they open and as soon as I started the car the AFR was around 18 at idle WTH?
As I pulled away from my driveway for the test drive the light throttle was so close in the AFR it was ridiculous.
Made a WOT run for about 3 seconds and when I checked the paper clip it hadn't moved. (they are not opening)
Looks like I'm on to something, so I'm going to pull the vac unit and see what's up.
It looks/acts like the secondaries were getting involved in the off idle somehow.
I'll pull the vac unit here in a few and take a look.
That explains why the #66 secondary jets didn't change much at WOT.:rolleyes:
