More than likely being in cali the yota carb is not vented to the atmosphere , the holley is and the gas is evaporating .
try this next time it sits for a long period of time .
Before starting it pull off the air cleaner , look down in the carb wit the choke open and pump the throttle by hand , if you see fuel squirt the bowls have fuel , if you don't see fuel then the bowls are empty and the car isn't going to start till you crank it and the fuel pump fills the carb up enough for it to start.
Once more for emphasis.
If it doesn't squirt, crank it over 10 times, then get out and check again. Repeat until you get fuel to the carb. THEN go in the car, pump the the throttle a few times and see if it starts. With no choke you may have to pump 5 or 6 times.
Once you know how long to crank BEFORE you pump the throttle, repeat it each time you start it up.
Or, install an electric fuel pump.
If you ever find yourself in a fair fight, your tactics suck.

HotRodRailroader, I haven't heard of the green gaskets. Think they make them for the original Carter carb? Are these gaskets in a normal carb rebuild kit?
Holly has just released them within the past month or two. They are greenish blue in color and saw them at a hotrod shop.

Spinning the motor builds oil pressure.
It also puts additional wear on every moving part until the REAL oil pressure builds after the engine starts!

So after wading through the thread here's what came out... It's a holley carb with no choke that sits for weeks at a time and does'nt fire right up.. ...And this would be normal under most conditions.. Add some fresh fuel down the vent tube as others have stated and illustrated...I have a very small funnel that fits right in there and makes the job easy pouring from a small cup or can.. And now with no choke you need to pump the gas while you crank and let it fire...If it stumbles pump the gas a little to keep it going until the engine RPMs come up and will run on it's own...And that means babysitting it for a while without a high idle circuit... I'm not a fan of adding an electric fuel pump{or a carb with no choke for that matter} for a guy who is'nt on top of all the carb troubles that come from long periods of sitting..You could easily turn the carb into an olympic torch if something is leaking or sticking with the electric pump pushing fuel... And on that note no matter what brand or how many carbs on the engine you need to watch the carb for any signs of leaking which means leaving the air cleaner off until it's up and running...I never just jump in a vehicle after a long slumber and start cranking without checking and watching the carb{s} as it cranks...All it takes is a dried up gasket,stuck float etc...And you've got big trouble...Good Luck...

My motor turns over about 4 times and I have oil pressure. I don't think there is much wear there. Besides that it doesn't take a lot of pressure to lube a non running engine turning over at very low RPM.
Well then, you're good to go, grind away!

Adding fuel by hand or electric is a band aid STOP the bowls from emptying by blocking the exhaust heat passage under the carb. Problem solved.
Ummm....the last two 440 Holley setups Ive had both had blocked crossovers and still exhibited this problem. After about two or three weeks of sitting the bowls were obviously dry. But if it was only a few days it was fine.

Blocking the heat riser in no way will stop this kind of problem. You can delay the effects by some amount (who knows how long) by blocking the riser and using an insulator under the carb. Still going to be dry after "x" days.
I want my fair share

I doubt that very much. At least after 50 years as a mechanic I've never found that to be true. The wear doesn't happen while cranking it happens after it starts until it warms up.
Actually I think we are both right to a degree. What I should have said was that the max wear occurs during cold start, from the time you hit the starter until it's running and the oil pressure stabilizes. From then until it reaches operating temp I believe it is still elevated but not to the degree it is on a cold dry start.
If the engine doesn't start and you continuously crank it, it stands to reason the rings will take more of a beating because the cylinders get most of their lube from the rods as they fly by so in that case I would think excessive cranking would cause the most damage.
I do know that Caterpillar sells a pre-lube pump that runs off the starter motor. You find them mostly on stationary industrial type equipment. A separate solenoid engages just the motor which drives a pump and after say 10-15 sec of full oil pressure it cranks the engine minimizing the dry start.
