[quote=davidpm;2055025]When you remove and clean your carb?
1. Are you talking about a 4 stroke carb?
Yes, although I have also done many 2 stroke & automotive carbs
2. Besides a can of carb cleaner and a screwdriver what do you need?
I have an air compressor which I use before the spray cleaner. A large, clean towel to put the parts on, lined up in sequential order, with "Up " sides "Up". Screwdrivers that "fit" are helpful, as is thin wire, like trolling wire.
3. Are any parts automatically damaged by taking it apart, like gaskets for example.
4. What parts may be reused sometimes but should be replaced.
I have been lucky in re-using what was there, by being very careful in dis-assembly. However, that being said, I think that buying a carb "repair" kit:
Tohatsu Repair Kits
would be best. IIRC, some automotive carbs have "check" valves which are spring loaded small steel balls, which can fall out in dis-assembly. A good parts diagram would be helpful. I think they can be down loaded?
Overall, suggest you go slowly,& very carefully. Pictures along the way may be helpful. As mentioned, line up parts from left to right in order of dis-assembly, with the "up side" up. Re-assemble in reverse order.
Cleaning may not always work. I loaned my 2HP Honda to my son in law. He didn't drain the carb. I attempted to clean the carb twice but could never get the motor to run spot on again. One new $100 carb did the job, it ran perfectly.
