When to increase the size of the main jet?
A general rule is to increase the main jet as long as each jet causes the engine to run as well as or better than the smaller jet in it before. When there is no longer any additional performance gain from the larger jets the jet size is too big – go back down one size. Note that the long piece below is not the main jet:
