and drive the car. RPM arround 2500. This is above idle circuit and below PV opening. I also unplugged the accerlerator pumps to have a true reading on the A/F meter

make your secondary part of the carb non functional when Tuning the carb. Take of this rod which connects Primary and secondary Butterflys. tune the Primary circuit first with your AF gauge. I bet your jets will be in the 75 range. if this circuit is ok connect the rod and tune the secondary...

i used those also for a decade now.Very tiny with M6 threads. Pump was hanging on 3 of them next to the Frame Close to the rear axle. But now i Change the Position of the pump because I have a sump in my tank now and will move more to the rear. Somewhere in the Corner between Frame at the rear...

thats true. As i said. I need a carb guru here... there a so many tuning possibilities. big pump. one or two? cam choices ( most people say dont use 50cc, or if than only with the brown cam but don't want to overfeed my engine). too much input.... confusing.

what plates? The adjustable jets? guess it might be a bit expensive shipping from germany to the states Well, i didn't install the carb yet. Waiting for a bunch of holley parts to restore it and make it usable. some threads are gone. don't want 50cc accelerator pumps so need new housings...

i got rid of the adjust a jets. changed needle&seats, found a mini hole in a float. 3 days adjustments took 20 liter fuel without driving one meter... :D so, jets are 75 front, 76 rear. 50cc accelerator with brown cams. This carb is only for track purposes ( car has man. Trans and a...

so. took a while. I measured 1,377 so the next known diameter is 1,375 from the books. diameter of the base plate hole ~1,68" ( 1 11/16 ) That makes it a 750cfm. correct? Well, since 3 days i try to make that sucker running. Already trashed the adjust a jets plates. But that sucker...

i am using a 15 psi oil pressure switch as on/off switch. Engine won't start or shuts of below that pressure.... ;)

i know. Carb not listed. and they dont respond since ever i wrote to them. e.mail, facebook.....

so, butterflies are all four numbered 172 w/ diameter of the base plate hole ~1,68" ( 1 11/16 ). really need to measure the venturies now... 4406 must be the "new" casting of the Blake Carb Company which modifies Holleys for circle track and Strip

Will measure the bores and compare with butterfly sizes out of the books. Thanks... :)

don't know if i keep them. Anyway, what i need to know is the size of the carb. 4406 stamped says nothing to me and the internet. Not even on the Blake carburation page...

Michael, those are adjust-a-jet blocks. Additional to the regular metering blocks which have no jets anymore.

Hi, i got a carb from a friend I can't identify. It has Blake and 4406 written on top of the main body. Thought it is a HP from Holley and modifyed by Blake Carburation. But not sure and they don't respond at all. I need the carb size ( flow rating ).Can you guys help me identifying? Need also...

so I would build an E85 carb besides the one for regular fuel. Electric fuel pump ( Carter ) I have since I'm running a 6.1 Hemi. Copper fuel lines a bit bigger can't be bad. Any idea where to buy such a connversion kit for a 750 Holley? Final question: Is the engine running better or...

oh, changes in ignition timing required?

hm, what if you use e85 and use regular fuel lets say every 10th filling? does this make sense? Any changes required then on the carb? How much is the fuel consumption increasing on street cars? And what are the requirements at all to change the car? Tank, Fuel lines, Carb specific parts?

No, trust me, there is nothing under my my like this. Only a single fuel line. I restored the car myself back in the days. My question was can I damage the pump when I regulate the pressure to -50% and is a return line technically necessary for this. I've read the Holley web page but it...

I have no carbon vent system. Emissions laws are not important for this here. This is just a technical question. Can you describe what you mean with "cavitate"? Sucking air?

I got a carter fuel pump (Carter #180-P4601HP) from a friend which provides 15 PSI. But I need only max 7 PSI for my Holley 750 carb. Is it possible to drop the pressure with a regulator to the half w/o damaging the pump and is a return line necessary?

Hi, what do you want for them? And would you ship oversea?

good question. Mine does the same. The Carb is fresh rebuilt.
