can anyone suggest a good mechanic for me to take my outboard to? im in the canton area. i thought maybe i could at least weed out some bad ones by asking here first.

Ive got a mercury 110 9.8 horse from i believe 1973. Id like to put it on my jon boat that i just got but it wont idle. its two cylinders, two stroke. It will crank up only on full throttle--after which it runs for about 45 seconds and dies. This leads me to believe the idle passageway is clogged. While i have a basic understanding of how a carb works, i dont know how to locate the plug i need to remove to clean this passage.

Also, im not even sure if this is the problem. There is excess gas that just pours out of the carb when im trying to start it. eventually it will crank with the throttle wide open and rev nicely to a high rpm--no question that its getting a good spark. So, this leads me to two additional questions. Should i suspect the float valve is stuck open, letting too much fuel in? Or maybe i have a massive air leak and the fuel simply cant get sucked in--unless its spinning at a high enough rpm to overpower the leak.

I checket the gasket in between the motor and the carb and tightened her down nice when i put the carb back on. Any other places i could be leaking air (note i checked the vac line and replaced it even though it seemed fine)

It may be worth mentioning that when i aquired this motor several years ago, we put it on merit 28 foot sailboat and it would crank no problem with throttle in idle position, and as i opened the throttle up it would struggle, never reaching full rpms. chunked her in the garaje and put the 5 horse johnson back on--it cranks first or second pull no matter what, rain or shine, even if it sat for a year. wish i could get that one, but its my dads and he will die before he gives that motor up.

any suggestions before i take this sucker to the mechanic?--maybe i should just junk her--after all its older than i am.

Sounds like float problem, hole in it or something. If your a diy kinda guy, found a carb kit and rebuild it. Not saying that's your only problem, but that's where you have to start.

hmmm. as always thanks for the advice, gotta decide if this thing is worth trying to fix--ten horses would sure be nice. i figure even if it costs a few hundred it would be worth it because i could get at least that much for it. ill goof around w the float before i take it in---the house im buying doesnt close for another month or so, so i wont be up in canton anytime soon anyway

buy yourself a repair kit for the carb and probably go ahead and get a kit for the fuel pump. I always try to do them together. if you have any questions or get stuck just be patient and post here along with searching the interweb for help and youll get through it i promise theres no black magic involved with making an older two stroke run reasonably well reguardless of what neighbors may tell you.

Just rebuilt the carb on my 94 Merc. they are easy to do and the fuel pump was also. Invest the money in a Seloc book (it's the Chilton manual of the marine world) If you want an easy start just buy some carb cleaner and spray it into all the ports you see and try to run it. but either your float needs to be adjusted, or the Idle needle is worn out. Fuel pump rebuild is almost as simple as it gets.
