2000 Johnson 30hp won't start

Long time lurker, first time poster here.

I have recently bought a boat that has a 30hp Johnson outboard on the back (J30RLSSR). The gentleman I bought it from advised he hasn't started it in a while.

In my quest to start the motor I have replaced and drained any old fuel in the system, changed spark plugs, checked the carby for any fuel issues, compression tested (110ish both cylinders). I still for the life of me cannot get the motor started, it doesn't even sounds like it wants to start.

My question is, what else should I be looking to check and/or have I potentially missed some sort of kill/stop switch that could be preventing the motor from starting?

Thanks in advance guys
 
So here's the thing, resting the plugs on the engine there's a spark, using the spark tester I bought there doesn't appear to be a spark, this could be due to the poor quality of the spark tester though (has a spring and what looks like a small bulb inside, this was the only one available near me though). So unsure on strength of spark at this stage
 
Are you operating the primer on the motor as needed for a cold start ??-----Not the primer bulb on the hose.-----Best talk to a shop to learn how to operate / start this motor.
 
You have spark / compression / crankcase compression / fuel so it should at least try to run.-------Perhaps check the flywheel key.

Hopefully the link worked. This is what the key looks like, the only thing I could think is it might be a bit worn down, however, one of the magnets in the flywheel was damaged, I'm thinking this may cause issues. Does anyone know a parts number for the manual flywheel, I can't seem to find it.

Thanks in advance
 
Facts for you.-----The key does not stick out very much.---Your key is not worn down I believe.-------The key is only there to position the flywheel for proper timing.-----The flywheel is driven by properly torqued nut.------And by proper fitting , clean and dry tapers.----Part # for a flywheel can be found on this very site you are on.-----They are proud of them.
 
To properly test your spark condition:
have "all" of the spark plugs removed when you test for spark so as to obtain the highest rpm possible.
The gap for the spark to jump must be a 7/16" gap.
Spark must make a real snap.

A spark tester can be made with a piece of 1x4 or 1x6, drive a few finishing nails through it, then bend the pointed ends at a right angle. You can then adjust the gap by simply twisting the nail(s). Solder a spark plug wire to one which you can connect to the spark plug boots, and a ground wire of some kind to the other to connect to the powerhead somewhere. Use small alligator clips on the other end of the wires to connect to ground and to the spark plug connector that exists inside of the rubber plug boot.
