Car in question is a carb'd 205 1.1
Starts fine cold, starts fine if its hot and you only leave it 2-3 mins. But leave it 20 mins or so if you pop into the shops it doesnt start great and you need to fiddle with the throttle peddle and crank it quite a few times.
Modern fuel and heat soak? Or is it another issue? Is it just the woes of having an old carb car?

id start with check for air leaks and fuel leaks , then get the carb mixture ajusted and see how that helps you,.

I'd go for heat affecting the fuel line. Back in the 70's I had a few cars do this and it was always fuel vapour lock.

Had this exact problem years ago on a an early 1.4GR 205. It was only a few years old at the time.
It was caused by fuel overflowing from the float chamber down the carb barrel and effectively flooding the engine. I took the air filter off and watched it doing it over about a 10 minute period. I assumed it was heat soak warming the fuel and causing it to expand. Never did cure it though I suspect lowering the float height might of helped. I did discover that it was a known and common problem.
The technique to get it started was to hold the throttle to the floor and wind it over until it would eventually come to life in a big puff of black smoke.
The car had a number of other irritating issues which meant that it soon went to live with someone else and we got a Mk2 Golf GTI which was soooo much better!

Get a renault 5 gt turbo fuel evaporater blower, was basically a fan in a ducted tube that the fuel feed ran through and was run when the car was stopped for 5 mins on a thermo switch, in doing so it stopped the fuel evaporating with. The engine bay heat
Well that was the theory behind it

Nick this has been a common problem on my cars for the past 20 years! my current n13 sunny does it, my 120y did it and every toyota starlet and 1000 ive had has done it. later carbs did have a fuel cut solinoid added that may have been an attempt to stop it but its not cured it in my cars. i would love to find a fix for it. lowering the fuel level has not worked for me in the past and has only made the hard cornering fuel starvation all these cars suffer from worse. ive alway found they will start fine using the 'flooded' foot to the floor technique. . and ive got use to the smell of unburnt fuel. |
