Jaffa Posted August 6, 2018 Report Share Posted August 6, 2018 Thanks to the good people at the Sunshine rally. Leaking petrol does appear to be due to a float full of petrol. Had a look on spares sites but it seems they are no longer available. Any ideas or do I just need to find a used but floaty float? Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 6, 2018 Report Share Posted August 6, 2018 odd most CD floats are sealed foam , obviously some are not strange major suppliers are showing them as NLA when Burlen stock them http://zenithcarb.co.uk/carbspec/carburettor/spares/id/4018/ pete Link to comment Share on other sites More sharing options...
Jaffa Posted August 9, 2018 Author Report Share Posted August 9, 2018 Great thanks. Can hear liquid in the float but perhaps it's just a faulty valve and I'm concluding it's the float because that's what was suggested to me. Either way too risky to use the car with the amount of petrol that leaks as soon as I stop. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 9, 2018 Report Share Posted August 9, 2018 Obviously if you can hear liquid inside the float theres a problem, ive only found black solid foam floats on stroms but who knows whats on your car , float valves dont last for ever and the dreaded floating slivers of hose that can jam the valve open plague some cars . Burlen are the people for genuine spares , so consider a replacement float and needle valve . http://www.buckeyetriumphs.org/?page_id=347 Gives good pictures and script to repair your carbs , theybare mainly for TR but the principles are common to pretty much all strombergs Pete Link to comment Share on other sites More sharing options...
Guest Posted August 9, 2018 Report Share Posted August 9, 2018 Jaffa, I agree with Pete re Burlen and I always recommend them. If you do need to get a float and I think you do then it will be worth getting a pair of their "stayup" ethanol proof floats which have been specifically designed to deal with such issues. Here is the link: http://sucarb.co.uk/catalogsearch/result/?q=stayup Regards. Richard. Link to comment Share on other sites More sharing options...
Jaffa Posted August 10, 2018 Author Report Share Posted August 10, 2018 Thanks for the help. Nearly a week and there is still fuel weeping out of the float. Link to comment Share on other sites More sharing options...

dave.vitesse Posted August 10, 2018 Report Share Posted August 10, 2018 If only there was some petrol resistance glue to repair the hole. Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 10, 2018 Report Share Posted August 10, 2018 Some repair kits include a array of float chamber gaskets, the profile eveloved and later gaaskets leave corners unsealed Do assume they all fit there are small changes which will give you a leaker. Burlen news says the stay ups are fornTR4 and early Triumph , best give them a call Do you have the brass tag number still on the carbs this helps The Cd ranges are in simple terms CD has a thames barrier ramp choke to make the piston rise and blockmthe intake CDS has a starting valve choke on the side of the front carb only , with tube to the rear carb mixture adjust from underside CDSE has starting valve choke and adjustment is down the dash pot the float base is just a cap under the fixed jet Can have temperature compensators on the front sides CDSEV just adds more emmission controls and air bleeds .

Jaffa Posted August 19, 2018 Author Report Share Posted August 19, 2018 Leak is just a weep from one seam of one float. Have spoken with Burlen and now have refurb kits but despite being listed, floats are no longer available. Am going to try super glue on the seam now the float is free of petrol. Petrol resistant, not sure, guess I'll find out. Link to comment Share on other sites More sharing options...

Petrol resistant, not sure, guess I'll find out. It's resistant but not permanently petrol-proof. you'll only have the same problem later. Ben's link looks good, the guys says its a genuine Zenith part, or phone Chic Doig for a good second-hand float. Link to comment Share on other sites More sharing options...
