Although my "almost a Prisoner" is Ford Moonstone Blue, I'm considering having the nose painted yellow.  Is that colour Lotus Yellow #7 or something else?  My Europa came from the factory in Lotus Yellow #7. and from what I saw under all the repaints, it was a cracking colour.

I like the yellow nose but unfortunately I don’t know the name of the color.  I believe the color scheme was Prisoner specific so perhaps Caterham can tell you what yellow they used for the Prisoner edition cars.

I believe its a standard Caterham yellow. Only the rest of the car was painted a special colour, chosen by Mrs Jane Nearn.

I have been in communication with Caterham regarding the car and Martin has been exceptionally helpful. He has been able to confirm the car is #42 of 47 Prisoner edition cars. The kit was delivered to the US in the summer of 94 and the engine and transmission were supplied by Caterham in early 1995. It’s nice to have a bit of history on the car. I was also able to get the build sheet and some shipping info as well. The folks at Caterham are fantastic. The only remaining mystery is how I ended up with a Prisoner Edition plaque numbered 14 rather than 42.

Martin has been helping me as well. Although, he can’t do anything at this time because all his files are in boxes for the big move. I think he has a great job and he seems to really enjoy it.

As to your #47 having plaque #14 it may be a simple case of each Prisoner car got a plaque but in no particular order. Case in point, I have a Ducat 900 SS Final Edition, #084. However, I learned that when the bikes were being built the plaques were mounted to the top triple clamp and then set aside until needed. It wasn’t unheard of to have a high number plaque put on a bike built weeks before a clamp with a much lower number was used. Meaning, there was no correlation between VIN number and plaque number.

Who couldn't be #6? All the normal stuff but no connectivity or credit to function. An exercise for developing skill rather than the original story line of  "prison" for opting out of an exit interview? Just a thought...

Have finally completed the first round of maintenance/repairs and have been doing some short drives. My wife had to tow me home from drive number 3, fuel issues. Since then I tweaked the carbs a bit and haven’t had the car quit on me since but the carbs need a rebuild with perhaps the addition of a fuel pressure regulator.  Suggestions on who to get the parts from is appreciated. It’s a 1700 Crossflow.


Took a friend out for a spin over the weekend. I believe he was terrified for most of the ride; said it was fun but preferred his 2005 Corvette.   This coming week an old motorcycle riding buddy is coming to visit with his wife. We’ll see what they think!

What are you using for fuel pump?

 

If its an electric, definitely use a 3 psi regulator. 

If you are using the cam driven mechanical pump, you shouldn't need a regulator, but some have disagreed.

 

There are many FRs from the various parts sellers.  Pegasus is a popular supplier for Formula Ford and Kent engine parts and they do have these.  Dave Bean Engineering is also excellent for parts and knowledge. You can call Ken there and he will know what you need.  

Your choice of FR may be determined by how you plan to locate it and the angles you need your fuel line to go.

I would recommend an arrangement where you can have a pressure gage on the output to verify the actual pressure.

 

Another thing you may be interested in is the Solex B26570 Pressure Stabilizer.  I got mine at Pierce Manifolds.  It's not a pressure regulator, but a surge suppressor.  It evens out the flow to the bowls so acceleration peaks aren't slamming the inlet valve.

 

Speaking of which, become familiar with adjusting your bowl float height.  This is critical to be correct for good running.  It's not to be assumed it is correct.  This can get bent out of adjustment itself and you can adjust this yourself.

From Pegasus:

"Our third recommendation is to CHECK AND ADJUST THE FLOAT LEVEL. In racing, the fast guys check the float level at least once every weekend. Usually they do it when they arrive at the track, because towing the car to the track can knock the float out of adjustment. Meanwhile, you've been driving your street toy over potholes and speed bumps (or even off-road), which hammers the float even worse. And if you just bought your carb, how gently do you think the shipper handled it? CHECK AND ADJUST THE FLOAT LEVEL. 

This is particularly critical on downdraft carbs (DGV / DGES), where just a 4mm (5/32") drop in float height can take you from plug-fouling rich to plug-melting lean. (A book on Weber carbs would come in really handy right now.)"

 

And my last word on pressure regulators, prices are all over the place on these.  $50-100 will get you a good unit; no need to spend $300, unless your engine is a science lab and that's what you're into.  But for fun driving, inexpensive (but not junk) is fine.

Great info. Thank-you. 
 

It is a mechanical fuel pump. I find I have fuel residue on my fender which needs wiping off after every drive.  I am going to try some fuel treatment first to see if that helps (as the car had not been driven much) and next a carb rebuild with attention to the floats. If that doesn’t work fuel pressure regulator would be the next step.

The pump must be replaced. I suggest an electric Carter pump but there are many options. Typical pump fuels contain ethanol which is hard on mechanical pumps. Electric pumps are generally more compatible with ethanol. A "last chance" filter near the carbs can prevent carb problems too.

 

Here is a discussion on electric fuel pumps:

I understand your difficulty in posting images to this site.  I have not yet cracked the code to getting it right every time.

I just got an email from Caterham about their standard yellow color.  I don't know anything about mixing paint, so I suppose I have to show this to a body shop to see if it is useful in the USA.

This is now known as firecracker yellow

We have a paint mix that is designed to match the yellow gel coat which is

Caterham Yellow          Caterham Mix

                                      AM44=649

                                      AM51=658

                                      AM7=668

                                      AM1=672.6

                                      AK100=1180.6
