I will try follow those instructions tomorrow , just one thing card out while adjusting ?
Jim

Yes, left the ignition on, popped me card out, phoned the good lady for an accurate time check off the radio clock at home to confirm it was still 2 mins out, i’d done the first 1 minute adjustment in less than 1 minute.

Done mine as well Juddian , simple when you know how , eh ? !!!
Next job adjusting same on non digi tacho , not the old ones with a dial but the last ones before digi came out ( 05 motor )
Ps I’m not totally thick just bone idle
Thank you
Jim
