Have a 8 hp tech. generator that will only run with the choke 3/4 of the way on what should I check ?/ thanks for the help

Two ways of doing this and one is easier than the other. If the engine runs fairly well on 3/4 choke add a half can of SeaFoam carb cleaner to the tank and let it run for a tank full. The harder way actually involves work and maybe a tool or two. Drop the carb bowl, clean it out with carb cleaner. Remove the needle valve and clean the seat, reinstall and don't loose that darn pin for the float

You I took carb off and cleaned it completely seems like it is maybe starving for fuel and this is one of those carbs that has no adjustment screws on it?

Air cleaner. Spark plugs.

Air cleaner is new. Plug looked good? Will that make it seem like it is running out of fuel?

How is the governor linkage?

Usually, this is due to a fuel restriction. Ensure the fuel is fresh and clean, and that the entire fuel system (gas cap, gas tank, fuel line, carburetor, etc.) is free of debris.

Done all of that. Every thing is free and clean and yes it dose seem like a full restriction I took gas cap off to make sure it wasn't a vacuum type of deal but made no difference..

Did you dose your fuel with SeaFoam or other carb cleaner like I mentioned in post #2? I have cleaned a B&S carb twice without any luck, then ran SeaFoam still not luck. The $196 replacement carb seems to do very nice, sometimes you just can't get all the junk out.
