Are these compression test numbers ok?
Did a compression test on my wifes 92 Accord EX with 240k on original everything. We run syhtnetic mobil 1 10w30, and do service it properly.
She said it was running funny the other day, so I decided to do a compression test on it.
The numbers are as follows in PSI- cylinders are going from left to right facing the engine, standing in front of the car with the hood open.
cylinder 1- 200
cylinder 2- 190
cylinder 3- 185
cylinder 4- 195
Are these numbers okay?
I've got another VTEC engine to swap into there from a 97 accord that I've had for a while, and I'm just waiting on her original engine to DIE to replace it.
What do you guys think?

Only 15 difference from high to low. I've seen better, but it's certainly not bad. I'd look for other reasons for it running funny. Maybe even a better description of 'running funny'.
BTW, the cylinders are numbered from the accessory drive end. So cylinder #1 is over by the accessory pulleys.
