Re: should 1993 90hp evinrude be tickety?
I have to admit that I opened this thread, just to find out what a "tickety" sound is. That said, TD's thought is about as close to anything that I would call "tickety." as any. When high tension leads (spark plug wires) short to ground, that's pretty much the sound they make .... "tick, tick, tick." You would not hear this at higher rpms, just because of engine noise. You might, however, sense some roughness in the engine.
I also agree with his suggestion to look at the leads, while running the motor in the dark. When doing so, watch the area around the rubbet plug boots, as well s the rest of the wires. Sometimes, you will get what are refered to as "carbon deposits" on the ceramic portion of the plugs. In light, they look like black dust. They have been known to provide a pathway for shorting from under the boots, to the powerhead.
