need help with 701

I just put a 701 out of a waveraider in my superjet and it has a msd enhancer and protec pipe. When I put it in the water it will run good for a couple minutes and then just cut out and not go above 1/4 throttle. I hooked the gas line from the gas tank right to the carbs and took the breather line off the gas tank so I knew it was venting and it still ran like junk. It seems the longer I let it sit the longer it will run good before it cuts out. I tried messing with the mixture screws but it doesnt change anything.

took the breather line off? no one-way valve?

It sounds like it thinks it is overheating? But if its not that then it sounds like a stator? Or maybe a bad MSD enhancer?
 
the tank, the line that goes up into the handpole i just took it off quick while riding to make sure the tank was breathing. If I take out the overheat sensor from the head will it work right.

if you do not have the breather line on the tank with a one-way valve, the tank will not build pressure and do exactly what yours is doin. go to an auto parts store and get a new one way valve...they look like this

i just cut the heat sensor off and coiled the wire up and zip tied it to something back by the ebox when i put on my head-no probs for 2 years of salt
