[1fast04neon]

boat was running kinda choppy... decided to take the carbs off and clean them, just did a quick clean going on vaca tomorrow. put all back together went real smooth. started right up but when u give it throttle it dies.. adjusted the idle and when gave it throttle it raced up to 7k and when i pulled the throttle back it stayed up there .pulled the key stayed running even pulled the sparkplug iwires and it still stayed racing until i backed to idle all the way of and it died ,,wtf.. and ideas at all??

That's what is known as a lean run-away. To kill it, pull the choke.

If you are sure of your abilities to rebuild/clean the carbs... go take it for a drive. It won't do that when there is a load on the pump. (and richen' up the low needle)

Tried to start the boat today and it wont even start..put new plugs in and still nothing..I wad reading it could b a air leak into the Carb??? I've cleaned many carbs out before and never had a problem.this just seams weird. I left all the set skews alone and didn't touch and of the adjustments...any ideas y she wont start???

I am curious to see what happened. Sounds like you know what you're doing. Personally doubt air leak.. assume you put some Loctite 515 Or whatever in there. Were the internal carb filters clean? Are you getting any gas into the carb? try a couple of teaspoons of gas in the spark plug holes before cranking.

Another thought, Engines need air, fuel, and spark. Air is simple.. it comes in from air intake. Fuel already discussed. So also check spark by pulling plug, grounding it and cranking. You should see a nice spark at the plug. What of the three above is missing?
