I reply to every thread Posted June 27, 2001 Share Posted June 27, 2001 Not my problem for once. A friend bought a W*******d this weekend (B*****D - he could have had mine 3 months ago). Car doesn't seem to have any paper history and all he was told was that it has a 1600 Xflow. (It's definitely a Xflow! - I spent enough time taking mine to bit's that I can tell by feel alone)The head has been changed to run unleaded and it looks as though the previous owner switched to twin 40's from a single downdraft at the same time.(there's a bonnet bulge and the carbs are new). The rest of the engine spec, head, cam etc is an unknown quantity. It's certainly not a screamer though. It has an intermittant bad misfire/loss of power. We've been round the houses trying to cure it and of course as soon as a potential solution is found the misfire disapears for 5 miles - then reappears. To get to the point - the 40 DCOE's are fed by the standard Xflow mechanical fuel pump. Mine always ran from an electrical pump. Will the standard pump do the job for what appears to be a relatively low spec engine? I think maybe not Link to comment Share on other sites More sharing options...
STEVE GILBERT Posted June 27, 2001 Share Posted June 27, 2001 It sure will and Caterham built cars just as you describe with 2x 40's and a mech pump.Mine is like this now (110hp).When I tested the pressure it was similar to a facet anyway. Have you checked the Float Height?/Tank vent etc All.Knowing1@talk21.com Link to comment Share on other sites More sharing options...
I reply to every thread Posted June 27, 2001 Author Share Posted June 27, 2001 That's me wrong then! I never even tried my engine on a mech pump - but then it was a 170bhp on twin 45's. Floats seem OK. I thought of tank vent - doesn't seem to have one! Link to comment Share on other sites More sharing options...

John Whyman Posted June 27, 2001 Share Posted June 27, 2001 What ignition is fitted? standard dizzy and contacts, or electronic like lumenition magic eye? The problem could be electrical and nothing to do with fuel at all. Own experience with 1700 cross flow was a damaged beam breaker arm for lumenition ignition causing similar problems, and also a broken connection to the alternator which was not visible under the insulator until rattled.

Graham Perry Posted June 28, 2001 Share Posted June 28, 2001 Have a feel/look under each barrel of the carbs, there should be a brass bolt going through the barrel that holds the chokes etc in place. There have a monotonous habit of falling out and will cause a misfire. I Wouldn't have thought it was mechanical fuel pump capacity related as they are good for about 150 BHP. Equally it could be all of the things mentioned above as well. Link to comment Share on other sites More sharing options...
