scorcher Posted August 16, 2016 Share Posted August 16, 2016 I'm wondering if and when hardened and thus leaking O-rings are renewed, whether the carbs. require a complete retune or would the status quo remain? Also does anyone have a notion as to the cost of a new set of coolant hoses for an X-flow ie Samco silicone or the standard rubber and which type is advised? Many thanks.

Jonathan Kay Posted August 16, 2016 Share Posted August 16, 2016 Also does anyone have a notion as to the cost of a new set of coolant hoses for an X-flow ie Samco silicone or the standard rubber and which type is advised?Silicone hoses last longer and come in pretty colours.Classic Silicone Hoses £78.Members seem happy with all three suppliers of silicone hoses. There's a Club discount from one of them.Jonathan Link to comment Share on other sites More sharing options...
Molecular--Bob Posted August 17, 2016 Share Posted August 17, 2016 If you mean the MISAB plates then you will probably have to re-balance them on the centre linkage but nothing else should change.With regard to hoses, the quality of the Caterham supplied rubber ones used to be poor with them cracking quite badly after 2-3 years. I got through 2 sets in 5 years before I swapped to zetec. Might be ok these days as I last bought a set 6 years ago? Link to comment Share on other sites More sharing options...
scorcher Posted August 17, 2016 Author Share Posted August 17, 2016 Interesting -thank you both. Link to comment Share on other sites More sharing options...
Molecular--Bob Posted August 17, 2016 Share Posted August 17, 2016 If you don't have MISAB plates ( http://www.demon-tweeks.co.uk/oncirrus/3/image/product/zoom/0123456789/0123456789/a-a99900-301.jpg ) but have the plastic spacer with an o-ring each side then I would change to the MISAB ones as they allow the carbs to move a little reducing vibration foaming of the fuel.

ECR Posted August 17, 2016 Share Posted August 17, 2016 Misab plates are a must really, the plastic plates with replaceable o rings can see the o rings sucked from their grooves during backfires. Link to comment Share on other sites More sharing options...
SJD Posted August 17, 2016 Share Posted August 17, 2016 Another for MISAB plates. Link to comment Share on other sites More sharing options...
Richard K Posted August 17, 2016 Share Posted August 17, 2016 On the subject of hoses, I got my 'standard' set from Red Line.They have been on the car for about 3 years. No sign of cracking.Richard Link to comment Share on other sites More sharing options...
Red Line Components Posted August 17, 2016 Share Posted August 17, 2016 So these Weber Misab Plates replace the black plastic mounts between the carbs and the manifold? Link to comment Share on other sites More sharing options...
andy_h Posted August 17, 2016 Share Posted August 17, 2016 Re the o-rings between the carb and manifold (where fuel/air mix passes through) - get the proper ones with the metal surround. Don't get the plastic surround type.when remounting the carbs back onto the manifold, don't do up the bolts on the rubber bobbins too tight, they should be looser than you think. If too tight you will get fuel coming out the carb and it will take weeks to find out why........ ask me how I know :)cheers,Andy Link to comment Share on other sites More sharing options...
OliverSedlacek Posted August 21, 2016 Share Posted August 21, 2016 The quality of the standard set supplied by Redline is noticeably better than it used to be (it's not often I can say that). I don't know when the spec/supplier changed, but the benefit of silicone hoses is marginal. Link to comment Share on other sites More sharing options...
