hi just as title, on the trailer starts ok, sometimes have to squirt a little fuel in the trottle bodies but get it on the water and its almost impossible to start,
ive changed spark plugs
changed fuel lines
checked carb filters are clean
checked fuel selecter valve
checked fuel pick up pipe and filter in the tank
ive got a decent spark. plugs are wet when i pull them
going to go back to the carbs tommorrow any ideas ?

Needles & seats are leaking (carbs). Replace them and re-assemble & leak-down test, re-set pop-off. Fine tune in the water.

Search the how-to section if ya don't have a manual.

ok so i ordered needle and floats x2 today but arent going to get them for several days, so i decided to get the carbs off and have a look at the needles and floats, they looked ok no grooves etc whilst i was at it i looked in the fuel pump and it was full of crap, so cleaned it along with the carbs and also set low speed to factory spec now it fires and runs but only when the choke is pulled any further thoughts ?

You need a pop-off tester. And clean carbs & fuel system. New *plugs.

Pull the fuel return line off, put a short line on the carb nipple, other end in catch clear bottle. Crank with wires on
the ground lugs, if it isn't fuel flowing good, the fuel pump isn't either pushing gas thru carbs, or can't suck it out
of the gas tank.
