I there, thank you for your contribution. So u reckon i may need to increase the fuel?
I don't remember saying exactly that. However mixture adjustment may be indicated if the problem persists AFTER you have
1) confirmed ALL your ignition settings are correct,
2) made sure the cooling system is properly filled, and
3) confirmed by an external thermometer that the engine really is running hot.
Regarding point #3, problems with the gauge, sending unit, an/or voltage stabilizer can all make the temperature appear hot when there is no real problem.
