MGB Compression Check - Easy to do!

Compression check on all 4 cylinders on a '77 MGB. Applies to pretty much all old engines. Mine came out to be in decent spec, but #2 is about 7.5% lower than the highest.
In car driving video at end!

Great looking MGB

I might be wrong but it looked like you forgot to zero out the meter after cylinder 3 - which s why 3 and 4 were identical. Still, I found the video very helpful since I’m about to try this for the first time using the exact same tester. Thanks.

Good catch. Looks like it was down a bit and then climbed. I've since put a new head on the B and it is ripping around pretty good.

Great video!

I thought that the throttle should be fully open when doing the test.

You can, but really you are just looking for consistency across all 4.
