Ok where to start , bought the boat with the head off of it .. put new head on it etc etc got the boat running .. took it out had a carb issue rebuilt carb found float had small hole . no problem , fixed carb. took it out 2 weeks ago boat ran flawless . When i was rebuilding boat , i put new coil plugs wires etc. i drove it last weekend and it just shut off on me coming up on plane and seemed like the more throttle you gave it the faster it would die. at this point i thought it may be fuel problems . sprayed the carb with starter fluid and still died ... the op temp was at 125 degrees . Was just wondering if anyone had same problem before i start pulling this thing apart. Any advice would be greatly appericated . thanks.

Welcome to iboats.
You have to figure out if you have spark. If you do, then its a fuel issue. How old is the gasoline and fuel filters?
You should avoid using starting fluid. I use 1 or 2 ounces of gas poured directly into the carb.
