starting difficulty when hot

[Dodgy Diver]

when cold the boat fires up first flick of the key , once its been running it does not like to fire up again , usually spins over about 10+ times before it will start again
it has a brand new edelbrock carb and fuel pump with filters
new ignition coil , leads and plugs

its a 5.8 ford Windsor lump , wondering if I need to fit a spacer under the car to stop heat transfer ?
thanks

I assume you mean carb?

the modern fuels are more susceptible to vapor locks so a heat shield may help. Keep the fuel lines as far as possible from any hot areas - exhaust etc

Heat transfer and autochoke settings were the problems in mine. Especially autochoke. Setting that up correctly was an artform in its own. Not sure if you have autochoke but if you do have a look at the choke setting after the engine has been run to temp but switched off.

 

[Dodgy Diver]

The choke goes off after 90 seconds.
I assume it comes back on again once the engine is off ?

Update . didn't notice but the carb already has a insulator fitted to it . so not much I can do to improve this ,

Did this problem occur after fitting the new carb?

 

[Dodgy Diver]

I can’t answer that honestly as the old carb was running so poorly I never had it running long enough to get hot

Long ago I had a cat that was difficult to start hot, the heat under the bonnet evaporated the fuel. Solution was an electric pump in the boot.

 

[Dodgy Diver]

the fuel pump is new and 2 ft from the carb
thanks

did you fit metal are carbon leads, I had a problem with the carbon leads breaking down when hot.
