^^ correct,,
itna small gap andaza sa achieve nahi hotha,,
take it this way one cm contains 10mm ,, and the gap is .05mm ,, in other words break a cm into 20 parts,, and the length of one part is what ur chonda needs,,
improper valve clearance can cause a lot of damages ,, so u better next time ask a mechanic to use it or change a mechanic,, there settingas are some times accurate but most of the times i noted those to be wrong,, they were almost more then .08mm sometimes .1mm ,, hope this helps,
