Today I bought a new set of spark plugs at a local store.I know they are not BOSCH and they are resistor type,but I tought anything new will be better than those old one.These are NGK.Now I do have spark at all cylinders but still no start.At one moment it sounded like its geting to catch but it was just for a short moment til I aded a pedal a bit.That got me worry.Did I just choke it with a pedal or it will got dead anyway. Thanks for your input.I did try with used good coil ,Now I dont know is it coil or new spark plugs,but who cares there is a spark there now.For the OVP it is new one replaced not long ago,just for the safety,but I did try exchange with the old one anyway just to make sure,but with no difference.Thank you for your try to help and if you have any idea just shot .
