  1. I certainly agree with Glenn.  Running the fuel line up over the hot engine is not a good idea. The original factory configuration has the mechanical fuel pump on the front left side of the engine. There is a T on the output of the pump. One side feeds the left carb with about 1 ft long line, straight to the left carb. The factory feeds the right carb with about 4ft of line that goes down around the front of the engine (around the timing chain cover) and back up the other side.to the right carb.  The bottom of the U in the factory line however, creates a trap that can accumulate dirt and crud in the fuel system and restrict flow to the right carb.  Both ends of this line should be routinely disconnected and blown out.  I suspect that someone discovered the clogged right side fuel line problem and thought that rerouting the line upwards would eliminate that problem but as Glen suggests, may have created a new vapor lock issue.  Normally the Cadillac V12 runs fine on alcohol laced fuel because the carbs, pump and fuel lines are on the outside of the block and below exhaust manifold heat.  I suggest installing a new line like the factory line. Consider cutting the line at the bottom of the U, add a T with a removable stub pointing down, so debris will collect in the stub and keep the line clear.

     

    There can be another problem with the fuel pump operation. the pump is operated by a push rod actuated by a lobe on the valve cam.  There is only about 1/4" of movement. The rod and the pump armature that the rod wears against can be worn down to the point that there is not sufficient movement of the pump's diaphragm to provide sufficient volume of fuel to supply both carbs at speed. It is likely that the right side will be starved for fuel due to the longer and perhaps restricted run.  I question whether the electric pump in this case would increase the volume of fuel past the mechanical pump with a worn pushrod.

  2. That is my point about the Underslung.  The opposite of the limited. Big, powerful and expensive but because the chassis and body are suspended below the axles it has a very low and squatty profile. Even lower than a typical model T.  A well known collector in my area, Bill Haines,  owned 3 or 4 Underslungs from the 50s to the 90s before his passing. He also owned The Baby REO as well.  I've also had the privilege of seeing an Olds limited up close and personal.  They are huge motorcars.

    I found this: Ingredients : Water, Dimethicone, Nomoxynol, C10-16 Alcohol Ethoxylate, Neatsfoot Oil, Lanolin, Propylene Glycol Butyl Ether, Fragrance, Sodium Metasilicate, Methylchloroisothiazolinone.

    Thanks for the info. Other than water & fragrance, I believe the same ingredients as a Twinkie.  Dimethicone, or as we all know it: dimethylpolysiloxane is a silicone.  Believe it or not, this particular flavor is non-toxic and used in foods, like that artificial, non-stick baking pan spray.  mmmmmm. I assume it produces a slick, non-stick exit shoot also, if you get my drift.  My wife and I swore off artificial flavoring/foods years ago. We use real butter, sugar, cream/half & half, etc. but less of it.  I've also sworn off silicones in my shop. I'm a true hobbyist who does most of my own work including painting in the same shop that I weld, grind, sand, and cut wood, as well as wax cars & treat tops & materials.  I don't have problems cleaning and mitigating dust before painting but silicone sometimes gets into my paint projects and causes fisheye problems.  I avoid using it, but that's just me. I'm sure it is a good product.

  4. Red lights could be for civil defense markings.  In the 40s and 50s the local town or county civil defense Marshall was a volunteer position similar to volunteer firemen and would be authorized to have flashing red lights like that wired with brake lights on their personal car. Would also have CD triangle decals on front and rear windows. 

  5. 20240319_133030.jpg.dcab88e22b97cfaf152fa12462556d56.jpgabove are what the fitting wrenches look like.   The soldered fittings are usually more substantial than flared ends. Make sure the mating faces are not damaged or cracked.  you may have to machine or sand paper the faces so they seal better.

  6. Do not use standard box wrenches or worse yet adjustable  wrenches on braass fittings, especially 100 year old fittings. You are likely distorting the fitting.  Buy a set of "flare fitting wrenches " These are special 6 point box wrench with one point cut open enough to slide past the diameter of the tubing and grab 5 of the corners of the nut. They distribute the force on 5 corners instead of just 2 opposite corners like an open end wrench which will deform the soft brass or copper nut and flare face. 

    Farrell and actual flared tube ends didn't  come into common use until the teens. Your originals are probably soldered on flare pieces like plumbing couplers/joints. If your tubing ends are tool flared on a 1911 car I suspect they are replacement.

  7. My dad tried to get one during the trial but his daily driving didn't qualify for the trial but the local dealer that was participating in the trial let my dad test drive it around town with my brother and me in the back seat. I was about 12 at the time and was interested in planes and cars and this was like both to me. There was a guy in Indianapolis who owned one of, if not only operating turbine cars. I believe he was a former Chrysler official. He used to drive it to the swap meet held at Marian County Fair grounds,  near indy.  It was amazing watching and hearing it drive in.  It's impressive to hear it spool up, fire up and accelerate away. I saw one at Hershey about 20 years ago. 

    I was impressed enough with turbine cars that I thought I could build one. I live near Akron, Ohio and back in the mid 70s I met a nephew of Art Arfons, who was breaking speed records at the time building turbine powered dragster. I bought a small military surplus, Aireserch turbine from them that was fun to fire up and play with but turned out to be more complicated than i thought to make that particular turbine power a car.

  8. The series 61 does not have the front fender chrome gravel guard. 62 series had a front chrome gravel guard and stainless trim on rocker panel, the 61 does not. The front gravel guard on this car doesn't look like the correct for 62 ? I suspect it was added to this car to hide a common rust spot where the splash panel behind the tire collects mud. 

    Also the upholstery is partly redone and not correct. It should be either all gray or all tan.
