Hope I didn't offend anyone with the subject, but I am annoyed as heck about the fact my prissy Holley-carbed 383 seems to require a White House summons to start sometimes.
Here's the deal. I have a freshly rebuilt stock 335hp 383. My engine guy thinks Holleys are the only carb on the planet, so its overcarbed with a 750, contoured bowls, etc. etc. Let me state up front I know zero about carbs.
The problem: If I start my prissy Challenger every week, it runs just fine. Two weeks, and it pouts and whines, blows some white smoke, but I can usually get it started. Longer than two weeks, and it pulls out its SEIU union placard and goes on a total walkout.
I hate this carb, and the tow truck it was hauled in on. My mechanic says gas is no good, and this is California gas on top of that, blah blah blah. I know about the gas. He says I just need to run it every week. Problem: I leave for 2-3 months every summer, and upon my return my simpering, pimply-faced cretin Holley isn't about to give me the time of day.
I would buy the argument about the gas, except for one minor problem; I have an 86 Toyota 22r pickup, carburated. When I return from my summer hiatus, my Toyota is as happy to see me as my Jack Russell- it fires right up like I never left. Same gas, from the same station that I gas up my spoiled-rotten Chally at. It would be nice, since I have upward of nine million dollars in this resto, to have the car show SOME gratitude and start for me.
So, obviously the Toyota carb, being only 27 years old, is engineering light-years ahead of even a new Holley. Don't mean to offend again, but that's what my anectdotal experience tells me.
If I could figure out a way to put that little Toyota carb on my 383, I would, except there are dozens of wires, lines and tubes coming off of it. I wouldn't care if my 0-60 times were 30 seconds, at least it might start.
PLease don't regale me with stories about how you let your car sit for six months, and it fires right up. Might push me into doing something nasty to my dog-breath Holley.

For three weeks???
I have an OEM AVS on my 340. If I were to go ut right now and try to start it, it would crank and crank and crank because the float bowls are empty. It doesn't matter whether the last time I fired it up it got warm or not. Pour some fuel down the throats, it runs great (well, it might stumble while the fuel pump catches up). The fuel in that car is at least five years old (probably older).
I have heard that Holleys were less prone to the fuel evaporating so it might be leaking down the intake. Let it sit for three weeks and pull the carb for a look... (smell the oil, too)

I have the original AFB that was on the car, a #4367 I think.
4367 is an original Holley for a 70 383 HP with manual trans. AFB is a Carter.

I bet your one of those guys that can't start a weed whacker ether.
I watch my some of my neighbors pull their pull starts until there heads pop off they don't understand how a choke or a engine works. I just laugh. I start my 20 yr old lawn mower on 1 pull.My 500 inch Wedge with no choke Demon 850 in dead of winter anytime I want no problem.
Read more about Chokes and Carbs then take what u learn and use it.

So, explain to me Mr. csr carb man, why my Toyota starts and my sacred Holley won't. All I want to know.
Like I said above the Holley is probably empty of fuel and the Toyota carb is not. There could be several reasons for this, but most likely the Holley is leaking the fuel out. There are some things that need to be confirmed, but the simple solution is an electric pump. Modern fuels are more prone to evaporation so today's gas will make the problem worse.
