I'm trying to clean the jets on my RP as routine maintenance they won't budge but that's another story !
The larger jet has 55 on it the smaller one 85, is that correct for a 34 with a Zenith 26va ? The cars run really well as is .
A spare 26va I have has 50 and 57 in it ?

Rich jets often eliminate flat spot and similar problems. Over a wide rich range power is little altered, but economy is. There is always the possibility someone has enlargened the venturi calling for larger jets. If done so as to preserve the venturi form may not be immediately obvious. Also encounter drilled and reamed jets. Can use the taper of a safety pin as a gauge.
