I want to do the engine compression test and for that I want to disconnect the pump.
Can you tell me how the ignition is switched off?
I think the compression ratio is 10: 1
thanks for your comments

I had read that it is better to disconnect the gas pump, although in other cars I had not done it. Thanks.Backinblack said
You only turn it over a few times until you hit max pressure then unscrew and move to the next one. Only an issue if a catalytic converter is fitted to the car as they don’t like neat fuel but you won’t have one of them. Sent from my iPhone using Tapatalk

This is the result with hot engine.
Order of the cylinders: 1,2, 3,4
(Kg/cm2) 13,1 – 10,3 – 12,5 – 12-5
(psi) 187 – 145 – 178 – 177
Whit oil
(Kg/cm2) 14,5 – 13,5 – 14,8 – 14-5
(psi) 206 – 191 – 212 – 205
What’s your opinion? The segments of the pistons in bad condition, especially cylinder number 2?
Thanks

Always fit new gaskets and valve stem seals as the rubber goes hard over time and it's a lot easier when the heads off.

You are sort of within specs.

with check did you repeat a couple of times? to to get an average? if within 10% of each other its normally fine.
Your readings like mark/briano says are showing issues on no2, but depends could be sticking rings or worn. Bad running can be variety of things, breather gauze blocked, dodgy leads, ht leads, my garage didnt remove the adaptors on plugs and as such the HT leads was sparking across.
But no harm in planning to remove and check, get gasket kit with head bolts and cylinder hone, minimum. At least its running.
