Has spark (I got shocked) has compression and I squirted some starting fluid in the carb but it still wont start. Cranks fine just no start. I also put a new plug in thinking maybe the plug went bad but didn't make a difference. I'm all out of ideas.
YT 3000 wont start

Try putting the old spark plug back in, hooking the plug wire up to the new spark plug against the head and cranking it. If the spark doesnt jump the plug you have a weak ignition system. I had a older briggs recently that was this way. Made me jump if i touched the plug wire But it wouldn't jump a spark across the plug. Took me a while to figure out. If your getting spark at the plug. I would suspect the flywheel key is next to check.

have you check the key in the flywheel to see if its ok. a sheared key can throw the timing off if it is a magneto fired engine. Also if the compression is low due to a valve not seating good.

Clean flywheel and coil?

I checked the compression and it was good. I dont remember what it was but is was well over 100, maybe 150? Weak spark is possable, i did get shocked but dont remember seeing a nice bright spark. What would that be like a coil?

in my situation i ended up ordering a ignition system tune up kit. Which included points, condenser and a spark plug. I not familiar with your exact engine. i doubt it has a coil or points. probably just a magneto

I don't know these new anti-Diesel or other devices, BUT, don't those work ONLY when shutting off the engine? Long as key is on and power to it, it opens and is ready to go? Then, when you release the key, engine stays running a moment more as the selinoid closes off the fuel and then engine dies from lack of it? That is how one on my V-twin I had worked. I have those on a couple other newer V-twins too, but never been into them or had problems. I think you should re-connect or replace that selinoid and wire it to work correctly. These modern GT's are getting just like the modern cars, can't just tear-off the junk you don't wish to fix and run w/out it anymore, you need the whole system to work to have correct functioning unit. First thing to find out is if it needs to be opened to run or closed, power on it all time key is on, or just to shut-off. Some basic things need to be found out before trying to fix.

If it's got compression and it won't fire starting fluid in my experience it's one of these 3 things (in order of most likely)
1) Plug not firing (ignition system failure)
2) Timing way off (although occasionally it might still "pop" on the fluid
3) WAY rich.

The spark from the plug (held against ground) seems kinda weak. Its definitly sparking but just. What would/could be the cause of a weak spark?

I've seen rust on the flywheel cause a weak spark.
