It was suggested to try rotating the MAF to change the airflow, I am trying to sort out why 50% of my hot starts are successful. I have noticed how much quicker starts are and smoother idle is when the MAF body is sitting in a diff angle.

If you have 100% starts, hot and cold, with a smooth idle, what clock position is your MAF located at? Right now my best is about 10'oclock, as viewed from upstream.

I don't know if it will help, but, here is a pic of mine. I have NO issues at all.

i have my LR MAF sensor rotated to about the 9-10 o'clock position, seems smoother an idle and just-off-idle conditions. but my sensor sits after a 40° elbow.

Mine is just like Jesse's.

LR MAF, sensor after bend @ 9 o'clock, no issues.

12:00 as per John, perfect idle, perfect starting

David is right, VR = 12, LR II = 10; this is due to the way the air travels to/through the tube, less turbulence for each. You should actually be able to move them and hear a difference in the idle, ever so slight but you can hear it.

I did...

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaawg

David and Bret, I'll try 12:00 again. This shouldn't be like syncing dual carbs..

those old 240Z carbs....damn!!!

ibkevin

hell no! I was thinking something much easier, like Weber 44's..

How about turning it upside down (6:00)? Any problems with that? I have some hood clearance issues.

aaaahhhhh ... those 240Z SU's .... brings back memories .... and in fact just a few weeks ago sold a complete '72 intake setup I found/remembered I had stashed away (intake, carbs, even the smog dashpots) ...
