[QUOTE="SumDumGuy, post: 359817, member: 12459"] I like to run my motors unlocked for the reason the guy you bought it from stated. As far as the engine tilt the straight up and down is an alright place to start. Run the motor fuel:oil at 50:1. There is some debate as to why the service bulletin was released to change the ratio from 100:1 back to the "usual" 50:1 (lack of lube running or lack of lube in storage) but irregardless 50:1 is safe. Perhaps someone with more real knowledge about the ratio change will chime in. If your motor has the 100:1 sticker it is, I think, in the year range of 1985 to 1988. Check this out... https://www.leeroysramblings.com/Lower_unit.htm https://www.leeroysramblings.com/Johnson%209.9_15.htm rrrr... just check out his entire site..... lots of good stuff! https://www.leeroysramblings.com/index.html [/QUOTE]
