Hello,
I have a 4 stroke Tohatsu 9.8A3 which coughs and splutters and sometimes cuts out if i try and accelerate quickly from idle. If I accelerate slowly I have no problems.
I have tried new fuel, new spark plugs, new fuel filter and changed the oil.
I have also cleaned the carby with carby cleaner.
I have only ever used standard fuel and am considering changing to premium to see if that makes a difference.
Just an observation I have found if I put my fingers partly over the air intake it aceccelerates quickly no problems but wont go to full throttle untill I take my fingers away.
I would appreciate some advice on what might be causing the issue and what to try to fix it please?
Cheers
