Hi,
Looking at an old Johnson outboard on Kijiji. Owner says motor is in great shape except for one small thing: low compression on cylinders. Can anyone guess on most likely cause of low compression for a motor of this vintage? Owner suspects that rings need to be replaced but suggests that he can’t find new rings anywhere. Wondering if it is much more likely to be something else. Comments/thoughts welcome.
Here is a link to the ad fyi.
