Hi all, I know it is contrary to the normal compression topics but I seem to be getting too much compression on my motor. It is a 2000 tohatsu 90 which I rebuilt. The powerhead was stripped to check the bearings, block etc and all were excellent. I took off the piston rings to clean out the slots and they were fine too , all rings went back into original position, as did pistons. All went back together and started 2nd pull on the manual starter, beauty I thought. It didn't seem too hard to pull start. Got the electrics connected and the start motor mounted which was in good nick too. Tried it but it couldn't turn the engine over. MAybe got it do do 1 rev very slowly , it would slow/stop on each compression. Checked the compression on each cylinder. All were showing between 125- 130 psi in each cylinder. According to the service manual it should be 116 psi. I have had the motor running in a tank for 30 min + on idle and it seems to be very good. the starter just can't turn it and i don't think it is the starters fault.
