Dose anyone here know how to solve a vapour lock issue ?

I have a Plus4 BTT which is only just run in and am having problems with vapour lock where if the engine stopes or runs out of fuel and when you go to restart it there's just no way. It wont even fire at all. The fuel just gets to the carb nipple and shoots straight back.

Funny thing is its not like its too hot either. I put my Exergen temp gun on the carb and it was only showing 185 when it was doing it.

The next run i did ritchen up the top end a couple hours but its still no different with the vapour lock problem.

The engine runs fine out on the track. Great really. Its just if it ever stops for any reason your not gona get it started again for at least the next 15 minutes or more.
