Tohatsu 9.8 4-stroke carb, and another problem

[buccaneer_35]

Hello,
Before I resort to the Guru's third option, I wanted to try this forum. Having read dozens of posts on the forum here, it seems as if I had the classic dirty carb (only idle on high). I pulled it apart two nights ago (and also repalced the pull-cord), cleaned the carb using Berrymans, and put back together. It started on the second or third pull, but I didn't have a water bucket, so I shut it down after 30 seconds or so. I go back to my shop today, this time with a bucket, and I can't start the engine. I also took the time, two nights ago, to change the engine oil and gear oil. This morning I put the Tohatsu 9.8 back on the boat, hooked up all the wiring, but still it won't start. My instincts tell me there is an electrical issue.
I know that it could be many problems, but I'm wondering if, to those of you with many years of experience, you are thinking, 'Oh, it's probably XYZ'. Is there a common mistake I might have made in putting the carb back together?

Thanks for you help,
phillp

Couple of notes here.

First, if you submerged the carb in Berryman's chem dip for 4 hours, cool. If you just sprayed it out, that was not adequate.

Second, if you ran the motor for 30 seconds without any water, you now need a new water pump kit. Period.

As for the no-start, you need to determine whether you have spark and fuel. What is your precise model/serial? Why did you need to change the recoil rope? If you have a EP type, you need to realize that you may have two stop switches -- one on the motor and one at the control. Either one can kill the ignition.

You must never, ever run a dry engine for such long period of time, will end melting the impeller inside it's housing and probably contributing with overheat premature wear on the head gasket & thermostat as well. You can start an engine to see if it's working before placing boat into water for max 3 seconds and then shut engine inmediately. Most new boaters don't realize that there is a delicate rubber part inside pump that is water lubricated, definitely outboards are not car engines
