ive always set mine to 0.8mm?? Yep. Me too. 0.8mm with a MJ or MS setup but I did use 0.6mm when on dizzy before going to MS. This is on an 8.3 CR and 99/100 RON Shell V-Power, up to 12 psi. Rich. Minivanless, but reluctantly happy living with the decision. There'll be another one day.

how do you know if they dont have the right gap start with .8mm if you start to notice a misfire around peak torque and you know its not fuelling, close up the gap .1mm at a time and see if it improves. as it stands i run .6mm but it didnt like the lean burn mixtures i used to run at cruise and part throttle when i had a .8mm gap. but had to go down to .6mm to alleviate misfires around peak torque. turbo 16v k-series 11.9@118.9 :)
