I have a 1996 Tohatsu 3.5 two stroke basket case. Piecing together this 3.5 and have a timing issue. It does not have points, it the cdi type. When I pull the cord and it fires the cord hits a hard spot and the motor sputters, like its fighting itself. I can tell the timing is off which as far as I know there is no adjustment. I tried a different flywheel, checked the key way and also a different cdi, same result. I have seen this issue once before and never could figure it out. Next I plan to pull all the ignition parts off a running motor and put them all on this motor to see what happens. I have had this motor completely apart as It needed a new top bearing. Anyone have any other suggestions?

Timing is controlled by the CD. That could be faulty. Never seen it, but it is possible.
Perhaps the carb is so lean that it acts like timing is off.
