Needle selection for Mk3 Spit

Posted By : Mark Raine, 01-Nov-2006, 03:16pm

Help!

I've fitted K&N's and a tubular exhaust manifold with club sports systems to a MK3 spitfire, I've kept the standard HS2 carbs, can anyone advise the correct needle selection. I currently have the standard BO neddles and the car lacks any power above 3,500rpm!!

Any advise, much appreciated

Mark

From the Triumph Tune catalogue for their Plus kit A which is basically what you have got, they state that H6 needles are required. I hope this helps.

  Hi Mark
  
  I had the same problem with my MKIV after i had fitted k&n's and a stainless steel exhaust and manifold, to solve the problem i fitted AQQ needles and yellow springs in my carbs and now it runs a treat pulling all the way round, i got the bits from burlem fuel systems on the internet (www.burlen.co.uk).
  
  Hope this helps
