OK first off the car has and had several problems that I'm slowly working on. Bought the car Feb 2006 didn't want to run much past 5 miles from home in the mornings. Would stall when coming to a stop, low power and jerky when driving, sometimes would clear up sometimes wouldn't in the next 10 miles. Always cleared up in the afternoon. I messed around with the engine off and on until it ran fine (HINDSIGHT, MORNINGS GOT WARMER). Drove all summer long with rare problems. Blew and had replaced head gasket after which the car was running rough. Front float on carb needed to be adjusted (some fuel leakage around screw). Last two mornings the car is back to it's old tricks (MORNINGS ARE NOW COLDER). Runs OK for about five miles, dies unless I hold my foot on the accelerator when stopping, very low power while driving, clears up 2-3 miles later.
Cruise control quit working when head gasket was replaced.
The car has new rotor/cap/wires/plugs/timing belt.
I probably need a rebuilt carb or a rebuild kit (leaky screw).
Possible culprits are timing advance, fuel supply or ???
Any recommendations?
Car is:
Honda Accord, 1984, 5 speed
218,000 miles
Carburetor Keihin
has 3-4 casted in the body
has ??90C 105020 on a tag

My guess is you should go for a rebuilt carb. The kits that I know of won't have all the possible parts that could be a problem at that age. Carbs ended because they were a pain but they worked and can work well, T

I would check the thermostatic air cleaner. I believe these air cleaners had a flexible hose attached that would go down to a heat shield/collector wrapped around the exhaust manifold.
A valve in the air cleaner’s snorkel would close via a temp sensor drawing heated air from this heat shield/collector keeping the air cleaner’s temp around a hundred degrees.
Without this working, moist cold air rushing into the carb would become so cold it would freeze the moister in the air on contact with the carb. Plugging air bleeds and passageways causing all kinds of problems, until engine temp was high enough to stop the freezing.

Luckly we haven't had any freezing days yet. Our mornings are in the mid to upper 40s Fahrenheit. And today the darned car ran just fine! I'll still check out the thermostat.
Thanks
Maybe I should just shoot it

Hopefully you didn't misunderstand; I don’t mean the coolant thermostat but the thermostatic air cleaner?
It doesn’t have to be freezing ambient temperatures for the carb to freeze up. It’s the velocity of the air rushing through the carb at temperatures close to or around freezing that does it.
40 degrees (or a little below), a bit of moister in the air, along with 2000RPM is the perfect mix for freezing up the carb.
And no gas line anti freeze won’t help; it’s the moister in the air that freezes and sticks itself to the carb; it’s not the moister in the fuel that’s doing the freezing.

I did understand, any easy ways to check this? I'll have time to look at it this weekend. The car ran screwy again this morning and we did have a bit of frost.
