Question
i have a 1954 chevy with a straight six 235 that will only run with the choke out what should i do i have changed the plugs points and wires  

Answer
Hi Bill:
The choke reduces air in the intake manifold, which causes
more fuel into the engine for quick starts and warm ups. If
you can not run without the choke out, you most likely have
developed a air leak in the intake manifold, which means too much
air is getting to the engine, which will cause the plugs to
fire, not combust and the car will eventually cut off.

Check around the intake and carb for cracks, breaks, loose bolts, etc.
Eventually the leak will get so bad that it won't run with the
choke out either.

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.
