[DeTomaso] problems with engine shutting down

[Asa Jay Laughton]

He mentioned in a previous post that it was the Motorcraft 4300D I think.  My first reaction at this point is to simply replace the carb.

I had a boat that ran the same way after sitting a year.  Ran nearly fine as long as I was over 2,500 rpm but try to idle and it would die every time.  I eventually rebuilt the carb.  The idle and off-idle transition ports were totally plugged from the crappy gas we now get.  My bet is this carb suffers the same, regardless if he does say he only gets good gas.  ALL gas will go bad at some point.

I say its the carb, but I could be wrong.

   Clarke,
   Most people will assume that you have a Holley carb. Do you still have
   the stock carb? Because that sounds like standard behavior on a 40 year
   old stock carb which was never very good when new and is now about 35
   years past its prime.
   Do tell?
