I have a Caterham Zetec, cams, TWM Pectel 216 HP setup. It runs very rich but has run very well.
Recently it started to mis at 4,200 and again at 4,700. At first I thought it might just be a cold engine. Today I took it out after a 20 minute idle to full temp.
It had the same miss in 1st, 2nd, 3rd and 4th. I didn't get to 4,200 in 5th on the public hwy.
Any thoughts before I spend money on dyno time.
PS I will have to pay someone else to do this as it is beyond my abilities.
Thanks for your thoughts.
