DT75 fuel issues carby leaking and low rpms

[rkylee]

Hi I have a Suzuki DT75 and after 4 months of sitting we took the boat out for a spin, it started fine but after 5 mins of cruising it stalled when we drop the revs, i took the cover off the motor only to notice fuel leaking out of the 2nd cylinder and if I used the primer bulb it poured out of the overflow, I then done carby kits thinking it was rubbish in the carby, I took the boat out again couple of days later and it done the same thing in the 3rd cylinder, so i again cleaned out carby's, 3rd try we get it on the water and no leaks but now it wont power over 2000rpms at full throttle, after getting it home again and flushing it on the muffs I noticed fuel coming out of 3rd carby overflow again, I'm at wits end and not far off selling the motor, any suggestions??
Regards Kylee

Drain and Clean the whole fuel system.
Dried up fuel and other trash can come out of the lines, primer bulb, and even the fuel pump after running and get hung up in the needles and seats.

and install a 10 micron water separator/ filter before going into the motor to protect from stuff from tank.
Some times the fuel lines themselves need to be replaced as they start coming apart due to the fuel eating them up.
And then clean carbs again real well
