more duration on the squirters cams ? try a tube squirters and 50cc pumps front and back them long runners need more fuel with one carb

Well, got to do more testing and decided to do a compression test because I am getting a lot of blow by on the driver side valve cover and found some disturbing #'s. The whole even side of the motor is is between 112 and 120 psi and the odd side #1 is only 52 psi, #3 and 5 are about 120 and # 7 is 147 psi. So I guess I will be pulling the motor for a tear down. I did put some oil in the #1 cylinder and retested it and it did go up to over 100 psi but after I fired it up it went back down to 52. Pat thanks for all your help on this. Any recomendations for piston/rings? Was thinking something between 9 and 10:1. Just want a mild street motor.
Thanks again
Scott
