Anyone here using an Edelbrock with the oil metering pump?

I looked at the vacuum advance nipples on the carb today and believe the 'always on' (always sucking) nipple would be great to hook an OMP line to. It makes more sense than the 'timed' vacuum advance nipple on the other barrel since its port is above the throttle plate.

The carb will sit on a plenum manifold so there is no need for metered oil in both primary barrels.

Anyone ever done this before?

By the way, Dan Atkins sets his OMP to the 9 o'clock position on his supercharged FB. Mine will be set to 9 too.

 

The port on the throttle lever side is full time vacumm, the other is a timed port

I was wondering if I should hook my OMP line to the full time vacuum. Anyone know?

 

I did that and boy does it smoke when I let off the gas. Take the oil tubes out of an old nikki and put them in the choke tower part of the edelbrock.

 

the stock nikki metering oil drips down the venturi

 

Hmm, it sounds like I could try the timed vacuum nipple. At least when I let off the throttle it won't pull a vacuum on the OMP. I don't think I have a dead Nikki around here... or maybe I do...

I have an interesting 1/8" NPT non barbed fitting that I think will allow a rubber OMP line to fit on it. I might be able to use it, or maybe I should save it for a Holley float bowl.

Hmm, I'll look at the carb again. Thanks for the responses.

 

tap fitting into the bowls, like on the old hitachis

 

Old Hitachis are like Nikkis. I have four Nikkis and four Hitachis to look at. I think only RB's Holleys have fittings in the bowls. I'll figure something out.

 

How did you run your linkage to the carb from the pump?

 

All you gotta do is wire the OMP to 50% open. It'll be a bit rich at idle, but since most of my driving will be at 25% throttle, the apex seals will get enough oil. Infact, my four port 13B has had this setup for a few months now. I'm going to swap carbs on it for a dellorto with a functioning OMP rod, but Dan's way does seem to work.

Just don't leave it floored forever and it's ok.

 

i thoguht the r100 and early rx-2's had this setup
it what i would do regardless i think its the best way
