Hi, Ive never done a compression test in my life, so here are the pictures of the results.

Are they good or bad?

I had a spark plug tester on and they are lighting up.

I've had the carbs off and cleaned the jets.

Next step is to put some fuel in and try starting it.

I will let you know how t goes.

Ok, starts idles,

One problem, there is a misfire. It's not enough to stall the engine an it seems to clean up at higher revs.

I will make a video and then you will see what I mean.

I was reading you can put a timing light on the plug lead, if it flashes then the coils are ok
