I went to mechanic.he said it is due to faulty electric slow jet but unfortunately I couldn't find it at near auto stores.

Change your mechanic he is not qualified enough if slow jet is faulty car will refuse to start

Engine RPM is too high. Slow down it to 850-900 RPM by screwing out the throttle stop screw of the carburetor with all the loads off and engine at the operating temperature.

Rpm is at 1000 and thermostat is there to maintain temp
