Default Re: Lack of power/rpm

Get an old motor manual for info on compression testing. cylinder leakage test, and shorting out cylinders while running. No way around not having compression. Must find out where, how much and why. then you know how to start a repair. Add to the list a vacuum test to see if exhaust is plugged. Off the used book store or U-Tube.
