Hi
My car is on carburettor, engine code 135B.
The problem is as follows:
When the engine is cold, the engine starts immediately and runs smoothly at idle speed.

After I go for some 100 miles at 55-70 mph and engine is reaching its cruise temperature, I stop and now the engine moderately shakes at idle speed, but hard enough for the dashboard to vibrate. If I stop the engine and try to restart in 30 seconds, the engine starts after a lot of cranking (10-20 seconds).

The air filter is new, the carburettor is untouched and spark plugs are new also (I changed them according to manual hoping to get rid of my problem).

So my question is: what do I have to check/clean/change/repair and in what order?
Thank you.
