Timing might need to be set at WOT.When asking question give info on the unit your working on. Make Model Year HP.This will help to diagnose the prob.Jerry

I didn't swap the fly wheel just trying to do a sync and link. It's sort of confusing even with the Seloc manual. It is a 70 hp Johnson 1988.

Rebuilt carbs, new fuel lines, idles fine on land with muffs.....also idles fine on the water but when you put it in gear it bogs out and dies.

Any help much appreciated. Thanks

yes the seloc is hard to under stand
i believe tash gave you alink on setting your timeing without running boat
i believe thats joes method .that i had told ya about .
if the timeing pointer has not been touched and you have swapped flywheels
you should not have to set timeing pointer .but if you want to be sure
its process is in your manual.if that part confuzes you pm me i just did mine it may be easier for me to explain it looked complicated ,but when it was said and done it was simple ,

sorry typeo i meant if you have not changed flywheels or moved pointer you should not have to set pointer

Is your timer base advancing BEFORE your throttle? This used to happen to me, and I found that someone who had been working on it forgot to put the timer advance spring back in. I've also heard of them breaking. They're cheap enough though. I wanna say 10 bucks list? Something to check out anyways
