No need to apologise, Ricardo.

We are all human and so we err...


I also suggest that you check that your fuel is not old (could have absorbed humidity from the air).
Just to play it safe, get a NEW jug of fuel, with 20% oil, at least half must be Castor and 0-5% nitro.

Make sure you start with the mixture setting quite rich and then, lean it down very gradually.


This engine should not overheat and has excellent cooling in general.
