Small outboard mechanical help?

[Lloyd]

mixture is the relation of fuel to the air not air to the fuel, the air volume per rpm doesn't change. so the screw changes the fuel in the air. rich is more fuel lean is less.
if the low idle were plugged the engine wouldnt idle and be very hard to start.
easy stuff first. check the linkages on the top of the carb. there should be two. one for throttle and one for choke. (choke may be by a dial or pull lever). they need to move freely. pull the bowl off and make sure the gas flow is good out of it and that stops when you gently push up on the float.because you said once under way its fine then i think these are ok.
if you are going to soak the carb you need to be carefull taking it off because of the gaskets. and because of the linkages. make sure to note what holes and springs etc go where.
try a good soak in carb cleaner, try to find someone that has carb soak. the spray stuff is crap for two stroke carbs.
buy a carb kit (needle, seat, bowl oring, gaskets, etc) check that the float doesnt have a hole in it by shaking it, there shouldnt be any fluid in it. again i think that all this is fine.
but do the soak.
next stop buying mix oil that you have to measure to each engine.
i highly reccomend "opti2". you mix once and it matches all 2 cycle mixes, plus it has a fuel stabilizer in it. so one gas can does all your 2 strokes. no guessing.
do not play with your adjusting screws unless you know how to reset them. return them to the starting place when you fiddle with them.
i hope its the carb. but.
with the carb off you may be able to see the cylinder walls. if you see up and down scratches then the cylinder and rings, piston need work.
its been my experience that usually the most common thigs beside the carb are the impeller, a little rubber astrick shaped thingy that is sticking or rusted on the leg drive shaft or the lower end bearings, usually one at the front of the prop drive shaft and one at the bottom of the leg.
how does it start hard or easy?
once started how does it rev up? warm it up first.
once under way how does it work?

Thanks Lloyd - I'll check that stuff on the weekend. To answer your questions:
Motor starts easy. Once is starts it revs up fine in neutral and idles well. I always warm it up quite a bit. However, if I crank the tiller right down to the "turtle", it stalls. Once under way it runs well enough if you keep the RPMs high, but doesn't seem very powerful (but I've never had something this small before, so that may be normal).

I'll keep an eye out for one for ya'! Jaydog is the one who always says that, so I'll ask him where he heard it.
