No Dorien.I have a lot of Holley jets 30 pairs. Do those work ?
Affordable Mike.
A Holley Carburetor has an advantage.Picking up this thread again... I am getting back to my shopping list from Summit Racing.
We all agree that there is no evidence to suggest the carburetor is at fault or defective? Buying a new carb would be a waste, correct? My current carb is a used 750CFM with a stock calibration.
The plugs indicate rich at idle. To clean that up: quality plug wires, gap at 0.045 and more initial.
The plugs also indicate leaning out at higher RPM. To clean that up: jet up across the primaries and secondaries.
I am surprised that I need to jet up on a combination with a very mild cam and 882 heads. Are the headers and intake enough to lead to that?
Also I should install a fuel pressure regulator.
I probably will go down that road at some point. But right now I am being careful and only replacing what really needs to be.A Holley Carburetor has an advantage.
Yes understand.I probably will go down that road at some point. But right now I am being careful and only replacing what really needs to be.
If there is no reason to believe there is a problem with this carb, for the moment, I will work with it.
There might be other more immediate expenses that could take priority.
Sorry Brian, I’m partial to my Rochester QuadraJets. I just like the basic principle on which they work - a big carb that works like a smaller carb until you need more . . . And then the secondaries are there to answer the demand from the pedal!
I amassed a pretty good collection of complete carbs from the mid 60s to late ‘70s mostly from Chevy and Pontiac with a few big block Olds and Buick’s. About 5 years ago I started organizing QJ parts like all the different chokes, choke pull-offs, all the internals and external linkages, the fuel inlets and the deep threaded inlets. All are NOS, reconditioned/plated and clean originals for the guys that need to pass the sharpest inspectors at the shows.
It would be easier to fine Tune fuel level with an adjustable Fuel Pressure regulator.Sooo, after a lot of searching and reading, I found something that might be of interest to the group.
Grumpy mention that I should check the float level with regards to being rich at idle. He also suggested to install a fuel pressure regulator.
The pressure regulator is on my upcoming to-purchase list.
Now, the float levels I am sure were spot on. I was meticulous setting them during my carb rebuild.
However... I have read since that the specific gravity of European fuels, specifically Belgium's Super 95 E-10, differ from fuel in the USA... affecting the float level. The floats are not as buoyant over here.
Hmmmmmm.
Yes way too high of Fuel pressure.
