I have been working on this 1969, 85hp Johnson. I have been going through it and replaced all the electronics. It fired right up but needs some fine tuning. I have the omc service manual and Clymer manual. I have needed both to get this far. The Clymar has alot of info that is useful to backyard mech. The omc service manual cant be beat though, as it covers the whole motor in about 50 very expensive pages (45 bucks on e-bay) The dont use three words when one will do! Anyway, I got the motor running, it shifts forward and reverse. Has good compression. I am now trying to fine tune it enought to put a timing light on it. I have made several attempts at following these instructions! I must have read this fifty times while looking at the motor. I am not getting it! The cabel in the remote also need some adjusting, which is further complicating things! It's seems impossible to line cam follower up on both marks at the same time! Can anyone tell me what I am missing in this? Synchronizing carburetor and distributor linkage Adjust the throttle cam. The center of the cam follower roller must align with the upper mark on the throttle cam just as the throttle begins to open. Align the marks on the distribator base plate and distribuator cap. If nessasary adjust the spark advance screw. Adjust the throttle cam yoke so the second mark on the throttle cam is aligned with the center of the cam follower roller The marks must remain aligned! Thanks!
