Well I was able to get all the fuel leaks fixed, SO I HOUGHT! I had a float valve that had a bit of something down in the seat. Cleaned it out (top carb) cleaned everything with carb clean and compressed air. Put it back together and it appeared to hold pressure. I replaced the carb fuel lines with clear fuel line so I could monitor the fuel. Raced out to the lake to do a quick test before dark. Started up fine idle a bit high 1050 rpm, put in in gear, idle was a bit high under load 800 rpm. Took off, my vibration calmed down a bit and then WOT ran great for 30 seconds. Then the motor ran like it was trying to pop wheelies. Quik surges holding 25 to 29 mph. I squeezed the primer bulb and it was soft. Not holding prime. Why not? When I replaced all the fuel lines I reused the FDV and the primer bulb. I checked them and they appeared to be working properly so I didn't think twice about it. They are only one way valves so pretty basic, I thought! I think 1 of 3 things at this point can have slow leaks. Fdv may not hold over a period of time, same with the bulb, and the fuel pump is faulty. Probably should test the fuel pump but it is farely new. Any good tests for these fuel pumps? Please let me know if my thinking is incorrect.
