I never had any issue like this with out of the box new carbs (950hp blower motors)
I mean "ebay special" so you saved a few bucks and now it doesn`t work and you have to spend all this time and work to get it to work right ?! I would have thrown it in the garbage long ago .
Being cheap never works out .

"There is hardly anything in the world that someone cannot make a little worse and sell a little cheaper, and the people who consider price alone are that person's lawful prey. It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money – that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot – it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.

I know the issue is the PCE metering blocks. thats a given.
the issue with them is the IFR and emulsion jets are too small. comparing them to the QFT blocks at the speed shop, they look to be a copy of the QFT blocks other than the jet sizes.
since the jets are undersized, I have a bag of jets coming along with a bag of air bleeds.
yes the blocks have the siphon breaks (or kill bleeds)

not going to go EFI, even if it was free. the amount of knowledge that I have gained over the past 3 weeks on fuel system tuning has been invaluable.

Play devil's advocate and pay yourself an hourly rate (Same as a service shop) for the BS head scratching you are going through and the cost of a tow call... a NEW carb may be the cheapest/ most reliable and safest long term fix. I am not soap boxing as most everyone has tried to make a carb work for the money but, there comes a time when the garbage bin is the proper course of action
2) Why knock EFI? It's simple, adaptable to most power levels and the kits work.... plus the fuel metering calibrations if properly set actually help the longevity of the engines.
My $0.02

1) Your still dead in the water trying to figure out a misfit/ miss matched holley carb... even if you do get it figured out - how reliable is the fix until the next problem? This thread is on page 3??

even the new vehicle of the wife's is on the 2nd throttle pedal, throttle body and throttle controller and the vehicle only has 45k on the odometer
not knocking EFI, built plenty of projects with everything from Westers tuned GM ECM's to holley DFI to megasquirt to 034 Motorsports EFI over the years. Just dont want it in the boat.
as stated prior, awaiting the new pack of air bleeds and emulsion jets from Summit to show up so I can see how the carb responds to the opened up IFR, PVCR and Emulsion jets.

I have to stand up for my fellow carb runners. I have a high compression, big cam motor that runs like a dream with a carb. I don't have a wide band so I have been gradually backing down jets and using an Otoscope to check plugs to make sure I haven't gone to far. I also have to admit I am running a Daytona Sensors ignition that has idle control through digital timing control. I don't have a choke and I boat in some very cold weather. My boat starts great, idles great and I can cruise down the river for an hour at 650rpm. Actually once it's been started once for the day, it's the fastest starting vehicle I own. I once ran my batteries down so my starter would only bump over one compression stroke. All I had to do is give the throttle a little bump and hit the key as quick as I could and that baby started right up. Try doing that with EFI. All one has to do is read the forums and the plethora of issues with EFI. I am an EFI guy, I have HPTuner software and have tuned almost all of my vehicles. I have installed EFI on one of my hot rods and yes I got it to run great. But then again so does my carb and it gets great fuel economy and fewer parts to go bad. All you need is a spare fuel pump and your good to go.
