OK, so it's not actually in the seven I'm building its in my (1994) transit van.

It starts first time when cold, but when the engine's warm it's a bit of a bugger to start. Needs full throttle and eventually splutters into life.

I've done the valve clearances and it runs great once it's going, just wondered if anyone knows what the warm starting problem might be and if it's easy to fix?

Thanks!

injection or carb, if carb what carb ?

Fuel vaporisation? heat shield the fuel inlet to the carb / injection and see if its better?

Mine was like that, the timing was advanced and the mixture was weak. Take your pick.

Normally rich mixture causes hot starting problems, might just be a clogged air filter

Thanks for the replies.

It's a carb (weber) with automatic choke.
Had a new air filter recently, the plugs look a good colour, possibly a bit rich but not running lean.

I'll have a go at doing the timing!
