Brian Deacon Posted January 11, 2016 Share Posted January 11, 2016 Hi. New to Caterham ownership. Have a 2002 car with Zetec 2 litre engine running on carbs. Under the hood I have a blue electronic box with "Blackburn Automotive Ltd" on it. Two plugs. Connected to a water temperature sensor, power, earth, and two what look like solenoids mounted just to the rear of the carbs. These have plastic pipes to the bottom of each carb. Not seen anything this on my previous cars. Anybody enlighten me on what system this is? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 11, 2016 Member Share Posted January 11, 2016 Welcome.That name rings a bell, but only faintly. More, please: Can you add a photo? (Just say if you need help with that.) Anything connected to the ignition? How does the rest of the ignition work?Jonathan Link to comment Share on other sites More sharing options...
Brian Deacon Posted January 11, 2016 Author Share Posted January 11, 2016 Not sure how to add a photo?This is not connected to ignition. That has separate control box. It does seem to be fuel connected but do not know of any carb electric connections other than throttle position sensors and its not that. It does have a temperature sensor connected, but its not an electric choke as not on the carb chokes (no cable either as these are disconnected anyway). Will post a picture if I can work out how to do it. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 11, 2016 Member Share Posted January 11, 2016 You can upload photos directly or link to them on an external server. Here's Ian B's excellent guide.Jonathan Link to comment Share on other sites More sharing options...
CharlesElliott Posted January 12, 2016 Share Posted January 12, 2016 Some sort of automatic choke? (Only based on what it is connected to) Link to comment Share on other sites More sharing options...
Brian Deacon Posted January 12, 2016 Author Share Posted January 12, 2016 It would seem to be some sort of cold start. The two solenoids each have an input pipe from the air filter and an output pipe to the intake manifold. Pictures now attached.This might explain my erratic and fast idle which cannot be reduced with the idle adjustment screw. If either of these solenoid operated valves has a leak I will always get air past the throttle butterfly valves.Take it nobody else has this fitted ?

Mark w Posted January 12, 2016 Share Posted January 12, 2016 If i wanted to find out what it did i would disconnect it !If it makes no difference it isnt doing anything and you can throw it away and loose some weight !Based on the lack of responses here and on Facebook it make be a " snake oil " product which may explain why the manufacturer is no more ....

Area Representative Golf Juliet Tango Posted January 12, 2016 Area Representative Share Posted January 12, 2016 Have you asked the previous owner? Link to comment Share on other sites More sharing options...
Brian Deacon Posted January 12, 2016 Author Share Posted January 12, 2016 The car came from Uk Sports in Canterbury, doubt if they would know. I have written to the previous owner but understan he has moved to France. May get the letter forwarded though. Link to comment Share on other sites More sharing options...
Brian Deacon Posted January 16, 2016 Author Share Posted January 16, 2016 Box, wiring and various bits and pieces now removed. Makes the engine bay look a lot tidier. Has made no difference to starting or running. Link to comment Share on other sites More sharing options...
