Just did a compression test cold and got 153 on left cylinder and 155 on the right. Is it a normal occurance to have a couple pounds difference between the cylinders?

I think within a couple is ok.

Yes, you are fine with a few like lbs.

 

Keep an eye on it, write it down and keep a good log of it whenever you test it. When you see a bigger difference in the sides, rip it down and investigate. Most will say a 5-6 lb. difference.

 

But your situation seems perfectly normal
