Well I don't get those numbers, not going to look it all up now but......as I said earlier a cheater plate system single 4 kit the jets were>
125hp....52n/59f
175hp....73n/82f
250hp....110n/110f...but the N solenoid only had a .093" orifice so that was very rich, it all was rich and thats not knowing what size the F solenoid was, today the F jet is around 5>7 sizes smaller@6psi, one would think you would halve those numbers for a split system, so>
50hp would be...around a 25n/25f for still a rich tune x 2 = 100 shot?
Your zex N solenoid orifice size needs to be checked along with the holes in your plates...all this = a headache when not going for 1 complete kit mixing parts but I think its more sensible to halve cheater jet sizing. 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. I would go into this a bit more if it was me, perhaps Bobzilla can suggest something better, he's good with N20 from what I've read.
