I say all this because if you jet 35n/28fx2 that=70n/56f to me thats near a 175 hit and very lean and if you don't come back **** loads on timing you could do damage of some kind.
Doubling the size of a jet results in 4x the area of restriction. Based on jet size alone (not accounting for flow dynamics), if 70n equals 175hp, then 35n + 35n would equal 87.5hp.
