the car has always had problems with starting when hot. i have fitted a spitfire fan, and a rubber hose from the fuel pump.
so now i am looking into a spitty rad the 22". which company's would people recommend? i do use canleys and paddocks for parts.

I would recommend addressing the real problem, not constantly up-sizing something unconnected. A bigger rad won't help with the heat soak from engine to fuel pump or carb.

Hot starting problems as in you have to turn it over quite a lot to get it restarted?

Do as Rob says and try to address that first. If its coolant isn't over-heating then all you'll do is risk bringing in over-cooling. Doesn't do the engine too much harm in reality, but your body will notice it in the winter and in the summer you'll have the same issues with starting you had before.

So, make sure your fuel system is all working correctly, check the route the pipes take isn't involving it sitting in an area of heat, heat shield the carbs, etc. Also keep in mind that modern fuel is more volatile than the stuff around when the car was built. Any sudden changes to how it's running could be down to what you're putting in it, so try a different brand for a few tanks and see if that makes any difference.


Acclaim - fully working and on the road
13/60 Herald - mx5 powered and other such fun things, legal enough...
Mk1 2000 - it's still alive, just sleeping
Expert 815d - the slug

If in doubt, do up until you hear the crack and then go another 1/4 turn to ensure tightness.

A compression check on the engine might be interesting. Also you could try pulling the choke out just a little on a hot start to see if there's any improvement and the problem is related to a weak mixture.....

the petrol I use is bp super unleaded. this petrol station is on a hill, so I bump the car . I have had put my old fuel pump back on the car, and this is better, but still does not like hot starting.
would it be worth moving the timing a bit? the car pulls lovely, and the mixture is ok. the only new thing I was going to make is a heat shield between the carb and manifold.

Does the engine temperature stay stable for long when stationary?

There should be some form of heat shield between the carbs and manifold anyway I think? Also some of the cars had an insulating piece between the engine block and the fuel pump.

There wouldn't be a heat shield on a Herald but there should be a 1/4" thick "gasket". There also won't be an insulating block behind the fuel pump. That was, I think, only introduced quite late, possibly for 1500 Spitfires.

True, but a heat shield wouldn't go amiss.
