[Healeys] over heat + misfire

[ATIGHTPROD at aol.com]

I have/had the same problem with my BN1. First off I pop the  
"hood"/"bonnet" so the hot air gets a place to exit, second I installed a new  radiator 
fan I got from David Nock at British Car Specialists and that  really helps 
with the moving of air, (No Financial Interest, it just works and  was easy 
to install) and third, I installed a Marine Bilge Fan next to my  radiator 
that sucks cool air from the outside and then blows it directly on to  the 
front carburetor float bowl. Since the heat shield doesn't protect the front  
float bowl in any way and it seems it was boiling the gasoline making the  
backfire and vapor lock, the cool air blowing right on it helps greatly. I 
still  get hot, but the car keeps running smoothly and once I get moving  
again, the temp comes back down and I'm good.
    I have an on/off switch in a box I made that  fits on my parcel shelf 
and whenever I get in traffic, I flip the switch and  save the day. I got the 
fan off of ebay, it was around twenty dollars if I  remember correctly and 
was white plastic. I just sealed the ends and painted it  with flat black 
paint, hooked on the three inch air ducting I got from Lowes and  I was ready 
to go. I actually use baling wire to keep everything in place and  this way, 
I didn't have to drill any mounting holes.  Best of all, it  works great.
    If anyone is interested, let me know and I will  send you pictures of 
where and how I mounted it. You just have to play with the  wires to make 
sure it's pushing the air in the right direction, but it was an  easy fix and I 
use it all the time now and it has saved more than one  drive!

My BN1  misfires, overheats, and is on the verge of stalling when sitting  
in
traffic at idle. I have to continuously pump the accelerator to keep  from
stalling. Crossing into Canada takes an hour in traffic at idle. Not a  
pretty
scene. Any ideas what to look for?
