carb questions

[cuda hunter]

Just asking a few questions.

12-14 below tdc timing at idle
3310 vacuum secondary.
31 discharge valve
466 orange cam on #2
30 cc accelerator pump
3.5 power valve
rpm at 920 average at idle
idle mix screws at 1 turn out
no smoke no backfire
tuned the hell out of the carb in my opinion
I replaced all rubber fuel supply lines between 36 gallon tank and metal fuel lines and the rubber hose between carb metal line and main metal lines heading to the rear.  All new rubber.
Also there was a cam added, cam bearings and lifters.

Took it out for a ride.
Idles great.
A little sluggish at low speed.
manual shift it, trying for 4500 shift but when I get to 3200ish it surges and almost dies until it can catch back up again. 
Did get it to 4K a few times but surged really bad. 
My thinking now is that I have a semi clogged screen in my electric fuel pump.
a clogged fuel filter large fram canister GFP-1 I believe with replaceable GFPC-1element.
or a kinked fuel supply line. 

Is there anything else I should check that comes to mind with this major surging issue? 

I don't know what my intake vaccum is at.

Do you have big cam/low vacuum at idle ? 3.5 powervalve will be too slow to open if you have anything over 8hg vacuum at idle, would explain the "catch-up" after initial acceleration. Maybe check float levels while you're at it.

I agree it may well be a fuel issue , could be a worn down fuel pump pushrod if it is a big block , I have seen this numerous times in the past

[cuda hunter]

Float levels should be perfect as I tuned the carb for some time. 

Not sure of vacuum.  Yet.

It's an electric fuel pump.

You need a vacuum gauge and a temporary fuel pressure gauge that you can read while driving the car. The 3.5 PV is too low if you have a stockish camshaft, but you have to know your vacuum readings to know that.

[cuda hunter]

After I replace the element and check the screen in the fuel pump I will do the vacuum pressure test and the fuel pressure test as well.   
I'm trying to find the cam card so I can note what the cam is.

PV is way off for a stock cam.

Get an idle vacuum reading and then divide that number by 2 and whammo that is the PV number you want.
