Mariner 4 cutting out

Hi, 1st post so hoping someone can help me

I have a 1990 Mariner 4hp (yamaha based), and it has been stored inside over the winter ( no fuel in it as used it up) . Put in brand new fuel into the tank with correct amount of oil and started up okay. But when I increase the fews at all, it starts to lose power and then cuts out completely. It will rev fine with the choke on, but not without it.

Any ideas would be much appreciated, as its time and money for it to be professionally repaired

Matt

Might also be a clogged fuel line/filter.

Might try increasing rpm (gently) while squeezing the priming bulb.
