Hi guys. Im a newbie on this forum. Im from South Africa and i purchased a OBR Pro Stock ported 30.5cc upgrade kit with a stuffer crank. All fitted well. The compression felt high . After running in the motor i tuned it . Put it up against a 30.5 hi rev king motor car and got a thrashing of note. The cars are of similar weight and both are tuned by me.
What could possibly be the problem.
