Hello all,

I had my 1985 13b just rebuilt and got it running. It was running a little rough so after about 10 mins I decided to do some checking, after doing a compression test the front rotor is getting 120psi the back is only getting 65psi so I feel the apex seals are not seated. I did take it for a drive and got it to operating temp brought it back and did a test again with same results. I am running 2 stroke oil with fuel just in case someone ask that question.

My question is how long should it take for them to seat?

Thanks for any help I get.
Greg
