hi @jaroslawpiwar5811, The short answer is that you're putting more of a cold substance inside the cylinders so the starting temperature of the mixture is less with more fuel (which also cools the cylinder walls in the intake stroke more than a thinner mixture). There is a longer answer which involves gasoline burn temperature and specific burn rate, power stroke period (burn time stays constant at the same rpm) and carburator mixture dynamics, but I think the short answer is better suited now - weekend :D. Thank you very much for the comment.
Why does enriching the fuel mixture cool the cylinder? Could you please explain this to me? Shouldn't it be the other way around?

@@f16spoon thanks a lot👍
@@jaroslawpiwar5811 Also lean mixture > more O2 per fuel > burns hotter
