Rough idle, stall, misfire problems.

Since you needed to rent a compression tester I'm going to assume that you never perform a compression test on any engines before. Check out YouTube on how to do a compression test. Remove all the spark plugs so that only the cylinder being tested will develop compression. The engine needs to be turning over quickly so make sure the battery is fully charged. Good luck.

I removed all the plugs and did the test again. Once again I still don't trust the testers accuracy + my inexperience, but the results are still telling right?
1-3 no compression
4 jumped to maybe 40
5 pumped up to 55 maybe
6 35-40
7 maybe 15.
8 the hose was too long in this test for me to get it to screw in.

I will try this test again with a proven tester and with a little more care, but obviously things are off. I have a video uploaded to show the results and how the engine idles. The first 10 seconds show the plugs (bank one clean, bank 2 every plug was dirty) the next 30 seconds show my test and the last little bit shows the engine at idle when I first picked it up. I've since had it higher like I explained in my original post. Anyway any pointers from here would be most welcome.

I would guess your compression gauge is not giving you correct readings. That engine would not start with those low numbers.

Ok good to know. I'll get a better tester and try again.
