Question
I have a 66 v8 stang, holley 650, msd distributer. I am a shad tree machanic but I am sooooo stumped right now. My car will start and run great till it warms up then it dies. When it dies it sounds like the choke turns back on but it doesn,t. I checked to see if there is fuel getting into the carb by opening the throttel body and I am getting gas. Its almost like starving for something, I checked for spark and I seem to be getting spark from the coil to ground. I there anything I am missing??

Please help,, I don't have much hair left.

Thank you for your time

Regards,
Scott

Answer
Hi Scott:
Although this could be a lot of things, you have to start investigating somewhere, and the most likely cause could be a Idle adjustment. If it idles down after warm up, then check for a stuck float in the carb. 2nd, check the air/fuel mixture. If is running rich (gas smell?), and finally fuel filter or pump that is restricting fuel flow after warm up. Maybe trash in the fuel filter?

Expertise

Visit my website at: http://www.classytransportation.com/ I can answer most questions about autos built in the 60's 70's and 80's. Specifically, Lincolns, Rolls Royces and the Excaliburs. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
