I service my two strokes myself. Usually if the motor is running poorly it is either rubbish in the carby or bad plugs.
Sometimes you clean the carby and never see any gunk but the motor runs sweetly after anyway. I rarely change the small fuel filter but give it a quick clean. You should carry spare plugs with your outboard.
I would recommend that anyone who relies on an outboard be proficient at cleaning a carby, replacing plugs, and replacing gear oil. To not be able to do so means that you will be reliant on wind if the motor dies. Usually I can get a simple motor like the OPs going in 10 minutes. Not being able to service a two stroke could be really unsafe if you need it one day.
I took my little 3.5 to Fisherman's warehouse, just down from Tomos when it stopped. I told them I couldn't see any spark and could they test the coils. After a few days they told me it wasn't worth it - they didn't even test it. I found an old coil from another motor, replaced it, and it still runs sweetly. I really hate paying lazy people to do a bad job.

Thanks Kankama
I can service a 2 stroke no problems. I have used and serviced tools, trucks and machinery, 2 stroke, 4 stroke and diesel, for the last 30+ years of landscaping. However I am time poor at the moment, it was 2 years overdue and wasn't squirting water. Hence the new impeller.
