what is the plug gap of morris minor 1000 - is it same to hack saw blade gap?

Its .025 in (.64 mm or in metric)

we gaping it using hack saw blade - is it fine?

Never tried a hacksaw blade

Sandun,
It depends on the hacksaw blade. The larger 31.5cm blades are 0.65mm thick and should do fine in case you have no access to a feeler gauge. The smaller blades are only 0.4mm thick.

i think gap is .024 to 026 in - .61mm to .66 mm so , if hacksaw blade .65mm ,what happen ?

it will be ok if its running ok then leave well alone

Use the centre part of a used blade that has some wear on it, and you'll be good to go.

You need to get yourself a feeler gauge as what are you going to do when you have to adjust the contact points or tappets. Never thought of using a hack saw blade !!

Hi when desperate in the old days (who said they were great ?) used fag packets and matchboxes to set the plugs at the roadside

The gap is not exactly critical - as long as it exists. And yes - a hacksaw blade certainly used to be 25 thou thick - it's probably gone to the ghastly metric mess now though..........

The gap is not exactly critical

But it made a hell of a lot of difference to the smooth running of my 803 when I closed them to the correct gap.

It will -if you have a low compression engine - and wide gaps, and possibly a weakish ignition circuit...........

How to gaping plugs of MM1000 -what are the tools ? and what is the correct gap ? Mr. Roy you say .025 gap same to hacksaw blade - so .025 in gap wrong ? the gap must lower than 0.25 ?

It IS 25 thou - go for it! Just very gently tap the hook electrode down till the gap is correct. If it's too small - gently lever the hook open with a small screwdriver. Do not ever touch the centre electrode with any tool!
