Well lads just checked my valve clearances and this is what I came up with, so what do you think?

I'd change the 0.13's and the 0.21, but that's just me.

Well there all in spec.

0.12-0.18In
0.21-0.27Ex

I'd probably just change the 21, but doing the .13's as well isn't going to hurt.

thanks lads for your replies I will probably change them to be on the safe side

yep, woudl change the 0.21's + 0.13's too (performed a valve clearance on my NC35 recently and changed the 'tight ones too).

If they're on the loose side don't worry too much but always change the tight ones.

I have just checked mine and come up with something a little concerning,I wonder if you guys can tell me what to make of it. Cylinders 1,3, & 4 are about spot on. Cylinder 3 has produced some different results. One inlet valve is bang on the other is 0.20mm and therefore 0.02mm out of tolerance and both exhaust clearances are out of limits, at 0.279mm each. It seems odd that three cylinders are OK and one has three valves out of limits.
Is it worth reshimming them to bring them back in limits or is it a sign of something more sinister?
