[Healeys] BN1/2 Hard hot start.

[WILLIAM B LAWRENCE]

I’ve done this just using a spray bottle of water. Seems to help. I’m using a DW heat shield and the problem isn’t quite as much of an issue. Now I occasionally have to wait a few seconds for it to clear, but only in the heat.

Michael,
I never tried the "mist" solution, but along with George McHarris from the soCal AH Club, we came up with a way to pretty much do away with the problem all together.
We installed a marine bilge fan that blew cool air directly onto the front float bowl. When caught in traffic and with the temps rising, turn on the fan and the car ran smooth. Before starting the car, turn the fan on, let it run for a few minutes and the cart started and ran smooth.
The best thing I ever did with my BN1 and was really simple. And best of all, I installed mine so that it could be removed easily and no holes were ever drilled.
Some where I have photos of my installation, but basically the fan was mounted next to and a little above the radiator on the driver's side of the car. A three inch hose drew air from right behind the grille, ahead of the heat in the engine compartment. The air then would be sent through another flexible "hose" and delivered directly to the front float bowl. I sat in traffic with the temperature getting close to the 200 degree range and never had a problem with vapor lock.
Worked great. And like I said above, it was a really simple installation with nothing permanent.

Like most 100's my early BN1 runs very well until I  try to restart it after parking for a few minutes after which it is hard to start and runs badly for the first mile or so.
This is of course a well known issue with these cars, which is caused by fuel boiling, and many people, including myself, have tried various types of heatshields in relatively unsuccessful attempts to eliminate this issue which has been exacerbated by the ethanol content of modern fuels.
I'm contemplating a different approach.
I have purchased an aftermarket windshield washer kit and I'm considering installing it with a button control to spray a mist of water onto the area of the main jet and bottom of the float chamber which I will use for a few seconds before a hot start.
The idea is that the water mist will cool the area and prevent the fuel boiling there.
Before I  try it I was wondering if anyone has tried this and if so what were the results.
