Little performance per liter

Hello friends, Kedault 19 with carburetor Kedo good to walk but is giving me 8 km per liter if someone can help ... It is the 1.4 year 1992

Adjusting the carburetor

What will be 2 bodies the carburetor, you should change the gasoline suppliers for some of the same caliber (new); Well, with more than 20 years, they will already be spent ... regulate the level of the Cuba (float) so that it is not very high ... check that it does not have air intakes between the lid and the carburetor body, and at the base to the collector. Spark plugs in good condition and the empty pulmon (is in the coil-modulus) that is not chopped because if it is not "back" point. Needless to say, you put a new air filter and that a valve adjustment is made. Greetings!!

** These engines usually spend between 8L. at 100 kms **
