no the flywheel key is ok.

I have good gap on spark plugs, put fuel down plug holes and nothing happens, doesn't even fire at all. Anything else that I could be missing here?

Thanks I will let you know how I make out.

I might have the coil wires on wrong. I will figure that out and check

Thank you

I have tried that and nothing. The wires that go on coils I’m not sure about. I’m wondering if the blue/ white stripe wire is positive or negative that goes on the coil.

I got the motor all put back together, compression is just under 100 on both cylinder. have checked spark which is good and sprayed a little pre mix into carb throat, still won't even try to start. Any ideas?

I got this motor all put back together and still have no wet spark plugs. I've checked the spark and its good but the motor still won't even try to start. I have sprayed a little premix into the carb throat as well, any I deas to what I'm doing wrong?

which wire is positive? white stripe or solid colour?

I was wondering if someone could help me please. I have a 110 HP mercury outboard and I can't find a manual for it. I need to know on the two coils I have a green/white stripe wire and a blue/ whit stripe wire, are those positive or negative wires? the other two are green and blue. Thanks in...

The piston rings are what give you compression correct? And if they’re bad could be why no compression. Would oily walls have anything to do with it?

The recoil is taken off right now and will be able to figure that one out. The motor. I put the flywheel nut on just to turn it and there is no kickback or anything but the pistons move up and down. Pistons look really oily. Is this maybe a bad ring problem?

ya the recoil failed for some dumb reason and doesn't retract but now my main concern is that I had about 100 compression before but now if I turn the flywheel by hand it turns with very little resistance. The prop turns while i do this and pistons move in and out.

So I went out and tried this morning and pulled her a few times and no start but now, the pull start came apart and feels like I have no compression like I broke something? there is little resistance when I turn the shaft and propeller moves when I do. The pistons still go up and down. Any idea...

That makes a lot of sense, thank you. I must be seeing the stops and the reeds are probably good then. I haven't learned much about reeds yet nut probably should. I forgot that I ordered new coils last fall along with a tester like the one you showed here and maybe try the new coils to see if I...

so looking down the crankshaft, the reeds must be almost touching the round pieces correct? and if they look like bending up, what does that mean please?

I have been using a tester with a bulb. What do I have to look at for better spark?

I have tried spraying premix into the carb along with ether, I know that’s bad but nothing happens at all. I’ve also been using an online spark tester and I do get spark.

Ah ok then. I took the flywheel, trigger and bearing housing off, looked inside and (if I know what the reeds at) they don’t sit flat. Any ideas?

I took the carb apart, soaked it and then cleaned it all up, motor doesn’t even try to start. I have a bowl full of fuel, compression and spark, plugs are still dry tho so no idea. Was thinking maybe the reeds but like I said I don’t see them behind the carb.
