I am a member of ASOG and hoped that I could get some help from this board. I recently spun a rod bearing in my engine and found a place that has a Japanese 420a. I would like to find horsepower and torque ratings.
Also if anyone knows the size of the piston, both height and diameter, would be very helpful.
Thanks in advance for any info you have.
