Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Fuel yes. No shut off valve.

Mechanic's Assistant: Do you plan on doing the work yourself?

How long has it been since your engine lasted started up and performed to your satisfaction?

Customer reply replied 1 month ago
one year at least
Technician: Donald, Small Engine Technician replied 1 month ago

Thanks for your response. Did you have fuel left inside your fuel tank from a year ago?

Ask Your Own Small Engine Question
Customer reply replied 1 month ago
no I replaced the fuel tank (it had cracked) and added new fuel. that is when the problem started.
Customer reply replied 1 month ago
I also changed the fuel filter.
Technician: Donald, Small Engine Technician replied 1 month ago

Thanks for this information. If your engine will only run if your carburetor choke is in closed position, this indicates that you have either a partially clogged jet or a partially clogged fuel passage in your carburetor. Your carburetor will need to be cleaned.

in addition I removed the fuel line to the carb and sprayed carb cleaner in it. also changed the spark plug.
Technician: Donald, Small Engine Technician replied 1 month ago

Did you notice fuel running from your fuel line, after you removed it from your carburetor?

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 1 month ago

Okay ...

I do believe that a good cleaning of your carburetor will resolve our problem.

Ask Your Own Small Engine Question
Customer reply replied 1 month ago
does that mean I have to remove the carb?
Technician: Donald, Small Engine Technician replied 1 month ago

Yes, you will need to remove your carburetor. If you will take pictures and make note, this will help to make reassembly much easier.

do I need a "kit" to do this?
Technician: Donald, Small Engine Technician replied 1 month ago

It is always best to use parts from a new carburetor kit after you clean your carburetor.

Ask Your Own Small Engine Question
Customer reply replied 1 month ago
can I get by without one?
Technician: Donald, Small Engine Technician replied 1 month ago

Maybe, if you are careful as you are disassembling your carburetor.

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 1 month ago

Some times you can reuse your parts.

Customer reply replied 1 month ago

Technician: Donald, Small Engine Technician replied 1 month ago

Sure. I will need to know the brand of your engine, and the model numbers for your engine.
