Old Cylinder Head Removal

[dom14]

did you do one test with the throttle wide open and the other closed?. tester had a bad day ( that time of the month?) liquid in the cylinders. doesn't look like a lot of carbon...

Yeah mate, but it was running rich(on petrol) and building up soot in no time when I was testing it.
I decided it was due to stuffed up carby, but now I think otherwise.

I did the test with WOT, but not sure what you meant by "the other"!!!

Thanx


P.S. Ok, my bad. I got it. You meant one test with WOT & other with throttle closed.
I didn't do a compression test with throttle closed at all!
What is the reason for that?
Since I always warmed up the engine before compression test, chokes flaps are fully opened while I was testing the compression.

Only thing I can think of that made a difference is that I replaced the stock starter motor with a Skyline one. The Skyline starter had more grunt for some reason and always turned faster. Not sure whether that affects the compression reading?!! The number of cranks were kept the same. I allowed the piston to go through all four strokes and was watching the compression jump with each stroke.
