Sticking 1975 Evinrude 85hp timer base?

I had no spark on 2 and 4 so I installed a new CDI timer base and the boat ran great for a day. The next day it was not easy to reach max rpms but finally after a few minutes the motor seamed to come alive. I have noticed that my timer base doesn't advance to the timer base stop screw when the engine is not running (going from neutral to max throttle with engine off). I did not get a chance to watch the movement when were on the lake. Is the timer base supposed to advance all the way to the stop when not running or does the movement of the flywheel help to advance the base? Thanks

Mine did the same thing - noticed the timer base coming into contact and chafing a clamp on the port side of the motor, persuaded clamp down with a screwdriver, and problem solved. Hope yours is that easy.

A common problem. Usually caused by old gummy grease. What did you lube it with?

Yes, it is supposed to go up against the full advance screw before dumping the carburetors wide open (they will slowly open a bit before then)

I lubed with white lithium grease. Hope I'm not repeating myself but if I understand F_R right I should see the timer base fully advance against the stop screw even when the engine is not running? With the lever out of the socket the base moves easily but moves very little with the lever in the socket and at full throttle with the engine not running. Sorry to be a pain.

Not sure i get this but if you mean you have disconnected something and the timerbase can move to the stop but if you use the throttle control it doesnt then that means something is wrong with your linkages or cable
does the timing base move easy?
Post a video if you can

No Title

Thanks for all the super fast replies. I went out pulled the flywheel and took her apart. Wiped off the grease, emory clothed the bearing carrier, used three in one oil on the ring and the timer base travels all the way to the stop screw and is NOW very easy to move by hand and jumps to the stop screw with the throttle. I can see how having these correctly lubed can make or break a day on the water. I am new to these motors and didn't have anything to compare the movement of a timer base with. My old timer base ring was actually melted and she was to say the least not easy to move. Thanks again!

The 3 in one oil is too thin for this application. The white lithium grease is a better lubricant.

Thanks for the advice. I will disassemble again and use some crankshasft assembly lube I have as it is the closest thing I can find to omc molylube.

Thought I would update this thread for anyone else that might have this problem. I called CDI and the tech said that I should sand the id of the timer base that goes around the bearing carrier. Started with 800 grit and moved to 1200. Didn't have to take off much but finally got the base moving like it should. Now she moves when I advance the warm up lever and the throttle. This was after pulling flywheel three times and disassembling and lubing everything else that was suggested.
