do you have access to ether or starting fluid? you could try that during hard starts. If its starts with ether the issue could be fuel, evaporation or vapor lock. if ether doenst have a effect, you issue could be ignition related.
just a thought.

By far .......... one of my best " Trouble Shooting tools " (starting fluid) ............... just be Smart & use it
correctly ...

I would throw in timing as a possible cause too. If its too advanced it can be problematic.

Guys,
I am grateful for your support.
ChevyII people are very kind.

Also I will check fuel and carb when it got hot. Thinking about percolation or similar thing. It was happened when I dove an old FIAT before.
Thanks!

The original points distributor setup had a resistor wire that ran from the big connector on the firewall to the distributor. This was designed to supply 8V so that the points lasted longer. The wire from the starter was there to supply a full 12V while the starter was engaged to create a hotter spark at the plugs. Since yours is an HEI distributor, you don't need the wire that goes to the starter. For HEI though, you DO need a full +12V to the BAT terminal on the HEI. The 8V or so that the resistor wire supplied is not enough voltage to run a HEI distributor properly, so it either needs to be replaced by a regular copper wire, or the HEI needs to be powered from some other +12 source. Check to make sure you are getting a full 12v when the key is in the start and run positions.

Hello guys, I am living in Japan and got 63SS small block 283 3speed AT recently. My ChevyII runs well and looks nice. I love it. It's quite rare in Japan.

I know I should read some articles about this issue. I am doing but I could not find out the reason. Also my English reading is low level. Could you give me any suggestion or recommended link?

Issue is...
Engine does not start after drove. For example, when I try restart after stopped by gasoline station. It's easy to start when the engine cold.
So I replaced the distributor, sparkplugs, plug wire and ignition coil. However it doesn't change. Sometime It restart after 3 or 4 times turned the key for start. A few times it did not restart and need to wait the engine become cold.

What should I check next step?

Postscript : Starter is cranking but hard to start the engine. It turns over but does not start.
Frist replace any sketchy batt cables and ground motor block straight to battery. Also install 2-4 gauge ground from motor to body I like 2gauge but 4gauge will do on front mount battery. On stock exhaust car,starter solenoid[relay] deteriorates with age and replacment can help. Exhaust header cars need to keep 2" gap from starter to prevent Hot start issue you have. A nu GM smaller perm magnet starter solved mine.

Check for starter (Heat) or Any other electrics. IMO fun project.. JR

the picture shows you the fuel set up my 283 is using --the regulator is the silver device just behind the fan and mounted by the manifold --- I used to have a steel fuel line running all the way from the fuel pump to the carb. Vapor lock is worse of course when it is hot outside --- If i shut of the electric fuel pump I still experience it.

Kon Ichi Wa Check the basics first: if the car has a Rochester Quadrajet 4 barrel carburetor they have two simple problems that would cause your issue. The floats in these carbs are very bad at being porous and sinking from being heavy with fuel. Change the needle valve as well if that’s the issue.
if you have had issues with the car also starting hard or being flooded in the morning there are screws in the base of the throttle plate. The cure is to seal over the heads with a layer of epoxy glue...they cause fuel to pool in the manifold when it’s parked. The fuel leaks past the screw heads.

Konnichiwa. I think here is a very kind and supportive community.
A few days ago, I tried to flooring the pedal during starter turns over, then I was able to start even if the engine was hot.
I go to the shop for talking how fix this and check about the heat soak is happen tomorrow.
Appreciate a lot of supports.

If there was black smoke at the tailpipe upon hot starting then it was flooding...too much fuel...if there was no smoke it may be “ hot soak” because the fuel gets so hot in the fuel line it turns to vapor
