      Can you give us  more information about :

      What Engine.. ?

      When.. January with 34 degrees or August with 100 degrees?

      Where .. Sea level or a High altitude track?

      Sprint or Road Racing?

      Without this information is almost impossible giving you a guideline

      Start rich and jet down (one jet at a time) until it runs like you stole it.

      Then make a note of the air density and then next time you go to the track do the same again – simple!

      Don’t forget that the air density and therefore your jetting may well change during the day so keep monitoring your engines performance and jet up/down as appropriate.

      Are you trying to keep what engine you have a secret? You will get a lot more help if you would give us a clue.

      As the title stated is no improvement, you could be running a moto, rotax, KZ, kid kart etc.
