The outboard (2.5hp, Suzuki) came back from service and is not working properly: when I push the choke back after a little warm up, the engine just dies. It seems to be OK, if I keep the choke at a "half-way-in" position. There is no way of regulating the choke: inside it is either "in" or "out". What might be wrong? What could be done to remedy this?

In any case, it may have to go back to the service guys... pity they are 60 miles away, though!

I agree it should go back to the people who serviced it although as LS says a good carb clean is probably all that is needed.

It does seem that a number of alternative jets etc have been introduced for this model over the years and in particular different jets since 2007.
Perhaps the carb could be updated to post 2007 spec, although this will cost several 10s of £s.
Official Suzuki outboard service agents should have all the info if this is a recommended fix for a "design characteristic" of earlier models

My guess is that the idling speed is set to low, it's a simple screw driver adjustment and easy to find if you take the cover off. I've found that setting the idling speed is quite sensitive, it needs to be done when the engine is fully warmed up, i.e. run for at least 5min under load and set so that you don't crunch the gears when moving into gear.

To start, back the throttle off, pull the choke fully out, and then open the throttle until you feel a stop, it's not very much 1/10 of turn or less. then pull the cord. mine starts 1st or 2nd pull. Then gently easy the choke in as the engine revs up. They seem to be good little engines, lots of power, but can be difficult to keep running after the initial start.

They also kick like a mule if you use too much throttle or choke when trying to start them when they are warmed up.

Hope this helps.

The choke should have a halfway position with a positive click. Mine has always needed a good warm up before doing without half choke.
