I do not have a set of Jet Drill bits sorry. Where would I purchase such an item given its specialist nature? Do you have a recomended brand for use by a hobbiest?
Secondly I am not sure what you mean by checking the float height. Would you be able to clarify and then I will do the necessary checks.
I am confident every removable part in the carby has been removed and thoughouly cleaned including the main jet, pilot jet and emulisfier. I will have another go at it on the weekend. The mower starts on the first pull when cold so I know the choke setting is right.
Ill await your thoughts.
