I am working on a LMH carb that mounts to a Tecumseh OH160 engine
The guy I got the engine off of said it didn't run right, flooded out all the time, said he put a rebuild carb kit in it but no change.
I have taken the carb apart and there appears to be something missing.
The nozzle is a service nozzle, has been replaced.
Right beside the end of the body where the nozzle screws into there is a small threaded hole and nothing to go in it. (pic)
What if anything is suppose to go in there?
