I have loss of power when the engine is hot its as though the govenour is not opening up to take the load All the usual checks have been made but the fault as yet has been located
If the engine is properly lubricated then the power loss will be down to either air or fuel starvation - is the breather hole of the fuel tank blocked?
You fail to mention the make - the model - and what you mean by the usual things - people have to guess.
