Re: Tohatsu troubles
"Running it dry" will leave a small amount of fuel in the bowl. Suggest you drain it instead. Just had the same problem with my generator which I haven't run for a long time.
I drain the carb after each use. Anyway, I dropped the bowl, which was perfectly clean, turned the gas on and manually "tickeled" the float up and down many times. It worked, ran perfectly without having to remove the carb.
Removing the carb and cleaning the jets and air passages is not difficult. Suggest you work over a large towel and place the parts top side up in the sequence, cleaning with a thin wire, compressed air and/or spray carb cleaner. No hands on experience with your particular carb but have done many others. Be aware of little check balls and/or springs, work slowly and carefully. Worst case is if your fix doesn't work you can take it, the carb, to a shop. Agree with the earlier post that modern ignitions are basically bullet proof.
