Please try to keep track of want is wrong just for learning purposes

I am still learning the scope part to

I am just commenting. it is very important that you see the top of each pressure spike to see that if they are even or all over the place. I don,t know if i am the problem or the screen shots but they look all chopped of to me. For comparsion on cranking compression waveforms go to atsnm.com then tr...

Put the pressure transducer in each spark plug hole and check the pressures

Exhaust valve opening should be 30 to 60 degrees before BBDC this is more like 5 degrees

Have you got a waveform running it apears as cam timming is of a little to close to tell on a cranking waveform

Thanks I always like to hear the end of the story

What does a good capture look like

So what fixed the problem

Have you checked the camshaft wave form against known good

i wander if there is some way to view this video if i dont have exess to youtube
can it be emailed
